Finally, in this 14c28n vs d2, we hope you get the right one. Though the volume of carbonitrides in the steel is relatively high. Thanks to its very high hardness (64-66 HRc compared to the average of 58-62 HRc), ZDP-189 can be ground thinner and sharpened less often. The D2, on the other hand, has a thicker and more durable blade that is better suited for tough tasks like chopping wood or prying open cans. Do honing steels as used on kitchen knives actually do anything useful? BD1 isnt terribly hard but sharpens easily. I forgot, I got the higher carbon steels will have higher edge retention from this website. Maxamets hardness results in incredible edge retention and a nightmarish sharpening and machining experience. Find your right answers here! Each of these contributes to a knifes overall performance. YMMV 14c28n vs. AUS-8 Steel . Would love to see where S7 sits on the Corrosion/Edge/Toughness meter. Its a costly and challenging process, but it makes extremely fine-grained steels, some of the best for knives, and makes some processes that were previously impossible a reality. https://knifesteelnerds.com/2018/12/17/cryogenic-processing-of-steel-part-3/. I am just grasping at straws here, but from the data you shared, it seems like toughness does increase faster than edge retention decreases: it is harder to get a very high edge retention knife that will still be somewhat tough compared to a very tough knife that will still hold an edge ok. we dont know. In that case the difficulty in sharpening would be the inverse of the edge retention rating. drop point There is no single category that means that a steel is more premium or better than another. Heres a brief description of their impact on the resulting steels properties. If you want to learn more than keep reading past the ratings. We and our partners use cookies to Store and/or access information on a device. It mainly made for knife and it high in Chromium for excellent corrosion resistance. This showed that XHP and ZDP-189 have significantly lower corrosion resistance than other stainless steels. have extremely high edge retention. These two knives are a little bit more than a pretty face. And given the recipe, it has a low number of carbides, the extra-hard microcrystals in steel that provide the hardness necessary for a stable and sharp edge. 14C28N and D2 steel are not the same. I used to work for a company that did reclaimed old growth lumber (swamp cedar, old growth pine and oak beams, etc) and we went through planer blades twice as fast as the cabinetry shop next door (turns out the neighbors like it when you put all the loud businesses together and far away), which mostly cut fresh cherry, oak, maple, hickory etc. The brand designed it as a carbide replacement. I have a couple questions, not directly related to this specific post, that I wanted to ask publically so that others could find your responses as well, so here seemed as good a place as any. 14C28N VS D2 Attributes: 14c28n: D2 . Both knives come at an affordable price for high-end knives. Stainless steels are another subset of high alloy tool steels that have enough chromium in them to have stainless levels of corrosion resistance. That way you can get into the steel ratings quickly. Both of those things are no longer an issue as I now have way too many articles and a book. Editors note: This article was first published in May 2015 and was most recently updated on May 25, 2020. Being stainless is not an on or off property, and some stainless steels are more resistant to corrosion than others. Its tough, but thats about it. D2 steel is a ordinary tool steel and knife steel. Liquid steel is sprayed through a tiny nozzle, solidifying into a powder. H2 Powder metallurgy steels with low vanadium content like CPM-1V and Z-Tuff/CD#1 have extremely high toughness. Toughness is the resistance to chipping or breaking. The main downside is the steel is more difficult to heat treat and can't go harder than about 60 or perhaps 61 Rc. We use a subsize, unnotched chapy test with 2.5 x 10 x 55 mm dimensions. 0.62% of Carbon: Makes knives harder and more resistant. Many steels are very similar to one another but go by different names from different manufacturers. Due to its higher Chromium content, S30v is a lot less likely to corrode/rust than the D2 Steel. are after the ratings. Rather than upgrade from D2 to M4 or S30V just drop the angle from 40 degrees to 30 degrees. Must-Have Bowie Knives for Your Collection, What is Micarta and What Makes It a Great Knife Handle, Top 8 Reasons Why Knives Make the Best Gifts, Pocket Clips: Carry Safely and Comfortably, Make a Knife Your Own with Accessories & Customization. (I think the 420HC estimate in that post was based on simulation or computer modeling, since you didnt spray testing any of the 400 series.) The D2 version is heavier and harder, but doesn't cut as smoothly. Thanks! Its soft, with very low carbon content. This is one of the fundamental tradeoffs in steel. Many steel ratings articles pay lip service to the importance of heat treatment without providing examples. By accepting all cookies, you agree to our use of cookies to deliver and maintain our services and site, improve the quality of Reddit, personalize Reddit content and advertising, and measure the effectiveness of advertising. My favorites of the high edge retention group are Vanadis 8 and CPM-10V. And for high toughness you want little or no carbide. Most of the discussion of how the ratings were generated, various caveats and details, etc. To choose the best knife for you between the 14C28N and the D2, look at the steel properties and ensure that they suit your knife needs and lifestyle. Other factors include how thick your edge is, how dull your knife was at the start, the nature of the heat treatment, and what youre using to sharpen your knife. In thick forms, like a fixed blade, 1095 isa tough, low-cost steel. He is the mind and writer behind Knife Steel Nerds, the go-to source for all knowledge about knife steel. Most steels use carbon to increase hardness, but 14C28N uses nitrogen, boosting hardness without the normal penalty of increased corrosion. 8cr13mov if proper slicing geometry its good budget steel if you dont rust it and no prying or screwing its ok cutting steel. D2 has a relatively high amount of carbon in its composition (1.55%), more than twice as much as AEB-L (0.68%), but most of that carbon goes into making chromium carbides instead of into solution in the steel matrix, leaving D2 with only ~0.5% C in solution and very large carbides that are good for wear resistance but bad for toughness. If youre looking for all all-around best knife steel, youd be hard-pressed to find one better than Bohler Uddeholm M390. Im a woodworker and Im interested in making better performing plane irons and chisels. Anybody know how the Sandvik stacks up against all these other steels. They were two different tests (different batch of steel, different person heat treating, etc). If you want for best steel 14c28n and others steel then you can ready 14c28n vs 420hc review. Some steel companies charge more than others. Sign up to receive GearJunkie content direct to your inbox. at least it has some vanadium over the 420hc. One is certainly anti-China bias, as you pointed out. When we plot toughness vs edge retention on a log scale instead we get a straight line that is a better visualization of toughness differences. Let the job at hand be your guide. These steels are typically used by forging bladesmiths, traditional folders, and some production fixed blades. does 1.4116 deserve the title of title of ultimate trash steel? : at a given toughness, magncut will have better edge retention in real life applications than s90v if it has optimal geometry (or maybe it wouldnt, just an example). D2 has been around for more than 20 years, an eternity in metallurgy terms. Ive found that most makers harden S30V too much, making it prone to chipping at the edge. Its very hard, tough, and corrosion-resistant. You also reported 8.6 for 440A in that post, compared to 8.5 in this post. For example, the Si space is blank for several of the carbon steels because they have a relatively wide acceptable range, not because the element isnt added. The ESEE had significant edge damage while the MagnaCut knife did not. Steel ratings are not about ranking steels in terms of what is better than another, but understanding the different balances such as toughness vs edge retention. edge retention can vary by several orders of magnitude depending on what happens to the burr. D2 seems to run at high hrc. VG 10 Steel, https://knifebasics.com/author/freelancer/, How To Choose Between The 14C28N And The D2, 14c28n Steel Is Good for Knife? However, D2 steel has better edge retention, while 14C28N offers a better sharpening experience. Another is that 8Cr13MoV is a generic name for a specific composition while AUS-8 is a name of a product by a specific company. 7:00am-5:00pm, 10am-7pm Tuesday - Friday Lately Ive been edcing one of those instead of a nice folder. Spyderco and Cold Steel have used it, though Cold Steel recently switched to S35VN due to availability concerns. Interesting. The high hardness makes it all but impossible to sharpen and machine. Steel produced in China is generally less expensive. It would be interesting to try to develop a conversation between /geometry/edge retention/toughness, so we could say e.g. Rowens heat treat on ESEE knives that use 1095 is exceptional; KA-BARs is less so. Goes to show that science not marketing or conjecture is what determines a good steel, 51shitty? It can build a knife that sustains a sharp cutting edge for long periods and is sufficiently wear-resistant. Hi there, Socould you please clarify which steel is the outlier and which is the line>. Hello LARRIN, do you have a Rough estimate on when ApexUltra (as well as more Magnacut) will become available? All rights reserved. Hi Larrin Your estimate of 420HCs corrosion resistance is different here than in your October, 2019 post on corrosion resistance testing: https://knifesteelnerds.com/2019/10/14/corrosion-resistance-testing/ : knife a with a toughness of 5 and an angle of 20 degrees will perform as well in edge retention as knife b with a toughness of 3 and an angle of 15 degrees. Instead, Vargo titanium uses a unique material called sintered titanium-ceramic alloy. D2 steel offers better edge retention and wear resistance than 14C28N. A cryo treatment and close temperature control is necessary to achieve those hardness levels. compare different heat treats of the same component, it lacks a theoretical foundation and its not clear how to relate it to the real world. s30v Still looking forward to magnacut making it into high volume production and use. Its so high in hardness that Maxamet knives usually ship with desiccating packages. But I think it would have much higher toughness than any of the steels on the chart. 14C28N vs. D2. quite possibly the best steel youll find on a sub-$30 production knife. I guess the question is whether toughness increases faster than edge retention decreases. Approximately the same hardness, yes. Here is the article by Larrin on 48 steels. in the correct place for the stainless-toughness-edge-retention graphic? Its called memory metal because heat can get it to revert back to a previous shape. Steels high in toughness are excellent for knives likely to see hard impacts, like large chopping knives. also the angle is by far the most important factor in catra testing, so such results might be irrelevant. Thanks Larrin, The Kershaw Leek is a most popular EDC knife that design by legendary custom knife maker Ken Onion. There one of the best reason that he is highly regarded as a knife designer. Hi Jimmie, thanks for your comments. Also I notice 1095 looks like another underperformer as there doesnt look to be any reason to use it over 5160 which I cant imagine is any more expensive than 1095. For example, see the chart below for how much edge retention can change with edge geometry for a single steel (in this case 154CM and CPM-154). These steels have sufficient toughness to handle thinner edge geometry. They tend to be relatively expensive and difficult to sharpen, as they have high wear resistance. There are significant differences between them because 14C28N is stainless steel, while D2 steel is a semi-stainless tool steel. Thank you. In some previous articles I have shown the balance between my toughness and edge retention measurements such as in the following chart, where the high alloy non-stainless are in orange and the blue are stainless: However, one issue with these charts are that difference in toughness is that a linear scale for toughness is a bit misleading for visualizing practical toughness differences. However, the relative difference in toughness between these different examples are similar. I made most of my leather knives from O1v (O1 with .20V) that I hold at 1475 for 15 mins and quench in 120-130 F AAA oil and Kevin Cashen is where those parameters came from btw. Though technically not a stainless steel at least 14% chromium, and D2 usually has 12% it's relatively corrosion-resistant. 1. As such, the performance of the steel is entirely dependent upon the steels being utilized. D2 steel is more durable than 14C28N, but it scores lower in terms of ease of sharpening and corrosion resistance. Using controlled furnace heat treating resulted in toughness around 23-28 ft-lbs at 61-62 Rc, while the knifemaker heat treated specimens were 7 ft-lbs or below. . The Sandvik 14c28n steel is ideal for the manufacturing of steel knife blades. S35VN Each steel was tested with a knife that was produced just for the test, and then sharpened the same way for each test (15 dps 400 grit CBN sharpening). Actually, Id be thinking 14C28N, but I want to leave stainless out. What would you rate the toughness of CPM-D2. Below shows pictures of a 61 Rc knife that was impacted with a 3/16 rod at different energy levels. The hardness of the carbides does not matter much unlike with edge retention. Many custom makers enjoy AEB-L, as its easy to machine but still has a high hardness, around 62 HRc. Only a few years ago Elmax was pricey, but competition has driven it down to reasonable levels, making it a decent value. With conventional steels this limited vanadium additions to about 4-5%, and this was greatly expanded when powder metallurgy was developed. . This is an American-made powder steel produced by Crucible and developed specifically for knives with the aid of the knife guru Chris Reeve (maker of the vaunted Sebenza, among other gems). Thanks in advance, Simon, For hard use everyday cutting in a packing company, Everything from fome, cardboard, tape, thick plastics, And plastic wrap that is against metal. This is also a powder-metal steel produced by American steel company Crucible. [Complete Steel Guide], What is Vg-10 steel?- [Steel Knife Review], The Difference Between 440c steel vs d2: Compared guide, Is 8cr13mov Good Knife Steel [Complete Steel Guide], Amazon Best Sellers in Pocket Knives & Folding Knives. Time and use have proven this to be quite accurate. 14C28N and D2 knives are affordable high-end knives. Because of their good edge retention, these steels are quite versatile in folders and fixed blades. Thats a little too far, but you get the point.). So for most steels they are given a rating at around 59-62 Rc, apart from a few steels that are never used at that hardness. The heat treatment techniques used by the manufacturer as well as the design of the blade itself play a huge role in the ultimate outcome of knife performance! There are still a few things I dont know but we have enough information to make educated guesses where data isnt available. Thanks. Also known as Z-Finit, Zapp produces this steel in America. Read about my tests in this article. at least it has some vanadium over the 420hc. High wear resistance steels are more expensive to buy and to process, especially since many require powder metallurgy. This is a midprice steel with matching performance. Some steels are cooked up specifically with this in mind and are very difficult to make rust. [Steel Knife Review], Best survival knife sword: 5160 steel Review, What is VG 10 pocket knife? I like it in the Seki City Spydercos, but I would like to know what ratings you would give it. In particular, I really care about the toughness / hardness part. Any idea where it would be on the hardness and toughness scales? Steels with only vanadium carbides have the best balance of properties because the hardness of carbide matters for edge retention but doesnt for toughness. You can read about my CATRA edge retention testing in this article. A quick check shows the compositions of these steels are nearly identical, so based on that Id expect them to perform similarly (differences in heat treat and blade geometry aside). The bump in hardness comes from precipitation of fine carbides in the steel, read an article I wrote on budget steels here, https://knifesteelnerds.com/2019/05/26/new-micrographs-of-42-knife-steels/, https://i0.wp.com/knifesteelnerds.com/wp-content/uploads/2021/10/stainless-toughness-10-19-21.jpg?w=757&ssl=1, https://knifesteelnerds.com/2019/10/14/corrosion-resistance-testing/, https://knifesteelnerds.com/2020/03/02/cpm-spy27-experiments-toughness-corrosion-resistance-and-more/, https://knifesteelnerds.com/2018/12/03/cryogenic-part1/, https://knifesteelnerds.com/2018/12/10/cryogenic-processing-of-steel-part-2/, https://knifesteelnerds.com/2018/12/17/cryogenic-processing-of-steel-part-3/, The Pros And Cons Of Stainless Steel Copper And Aluminum Brewing Equipment SanctuaryBrewCo, https://knifesteelnerds.com/2020/05/01/testing-the-edge-retention-of-48-knife-steels/. 52100 14C28N steel is as a result of a more corrosion resistant version of the 13C26 steel. I would love to see a Tungsten-Carbide blade (like Sandrin is using) and how it compares for Edge Retention, Toughness and Corrosion Resistance especially how it compares to s90v. Among Vancron SuperClean, Agomi #1 and Shirogami #1, Which one tends to have finer grain size and Sharper edge? It's like the difference between average 420HC and Buck's 420HC with the Bos heat treatment, only from a better starting point. The biggest change that is seen with powder metallurgy in measured properties is in regards to toughness. The value being slightly different doesnt mean its an outlier or measurement error. Keeping in mind that I have a well rounded Set of sharpening skills. AEB-L and 14C28N are the best in the high toughness group. On the other hand, edge stability in terms of micro chipping and edge folding is also good. Why do you give a coin with a knife as a gift? Despite its wonderful performance, XHP is actually not terribly expensive compared to other high-end, all-around performers. Although it should be noted that there doesnt seem to be a need for the stainlessness on a wood working tool. However, in our testing there is a reduction in toughness by using the high temperature range rather than the low temperature range, such as was found with CPM-CruWear (Z-Wear) or CPM-10V. Is there a reason SG2/R2 are not included in the lineup, despite being one of the most popular ones? In its most basic form, steel is just iron and carbon, but people have been studying, experimenting with, and perfecting steel with other elements for specific applications for millennia. Great for tensile strength and Edge retention. The unique process used to make LC 200N results in a fine-grain structure. Why do knives make the best gifts? Notify me of follow-up comments by email. Nitro V is also significantly cheaper than many other steels with this level of performance. Question. If you are looking for a high-end knife on a budget, the varieties of both steel will serve you. So you can estimate how much a change in hardness would affect edge retention by following the slope of those lines. Therefore I will be showing the ratings of the steels graphically in terms of toughness-edge retention balance, where steels that are high and to the right have the best combination, and you choose the steel based on the level of toughness or edge retention necessary for the knife. Other factors that can be added in are corrosion resistance, hardness, and cost. show very different and even inversed behaviour (e.g. 14C28N, designed by Sandvik at Kershaw's behest to have the edge properties of 13C26 but with increased corrosion resistance by adding nitrogen and chromium. It also improves edge retention and strength. Cookie Notice Its easy to sharpen. and why would anyone want to use it when 420HC looks so much better for a simple stainless steel option. Below shows charts summarizing tests of different steels for the major categories discussed so far, low alloy steels, high alloy non-stainless steels, and stainless steels. What carbon/tool steel would you choose for a survival knife if a PM steel was too expensive? The knives are ideal for both indoor and outdoor use. You can read an article I wrote on budget steels here. Vancron has a very fine microstructure so it would be tough to beat. As with high alloy tool steels, the amount of vanadium can be a shortcut to predicting the general level of wear resistance and edge retention. Fine-carbide knife steels. Your email address will not be published. Contact me if you have any questions or input! This list is not exhaustive, so check out some of our rating tables for more information on whatever steel youre interested in. Did you change the estimate based on more testing? It should get an ultra-sharp edge for easy cutting, hold the edge for long for easy maintenance, and have a sturdy and ergonomic handle for comfort and to prevent accidents. They differ little in composition and treatment. I think you wrote an article a bit ago on CTS-XHP and concluded that like D2 and ZDP-189 it wasnt really stainless (although stainless is a somewhat arbitrary line). blue steel I was recommended the Rat 1 in D2 and I also found that I really like the design of the Ruike p135 and p128. S90V Its hard to say. 420HC, 420, and 5160 all offer off-the-charts toughness. This doesnt necessarily mean they have terrible toughness, but they have limitations. Theres a green triangle at about RC 60.5 and toughness over 40. So hard vanadium carbides means you get more edge retention for a given amount of carbide. The 14C28N stainless steel from Swedish manufacturer Sandvik is considered an upgrade to their 13C26 steel (described below). I see very little about cryo outside of journal articles, and I wonder which knifemakers use it. That is an air-hardening- high carbon, high chromium tool steel. Custom maker Brian Trudeau uses Nitro V, and Massdrops Perpetua design is the first production knife to sport it. 9cr18mov vs 14c28n. Diving into the pool of knife personalization possibilities is a fantastic way to fend off the post-knife-buy blues. Id like to quote some of your toughness, edge retention and corrosion resistance for balanced midfield steels, including yours, in some data tables. Powder metallurgy is a technology designed to maintain a small carbide size. In many cases, the D2 edge sharpness may last a bit longer. Below, weve listed some of the attributes you might want out of your steel and given some examples in both the more expensive powder metallurgy steels and more affordable conventionally produced steels. The table shows combinations of knife steel properties for different classes of steel. Perhaps a bigger issue with the upper temper is for stainless steels, as there is a significant reduction in corrosion resistance by tempering at 1000F instead of 400F. If youre having trouble finding the steel you want, see if another manufacturer makes something much like it. But in my experience, it has been nothing but great. On the other hand small but mighty, the pocket knife provides both in professional performance and in arresting good looks. Despite its age, its a truly superior steel. MC66 In my experience, it will tarnish and discolor quickly. It also tops out around 60-61 Rc like LC200N and needs relatively careful heat treating to even be that hard. I am particularly interested in researching knife steel, knife properties, and brands. On the flip side D2 steel is much harder than other steels in this category such as 154CM or ATS-34 and as a result holds its edge a little better. I guess that was before I started reading. Why wouldnt it be possible to make a damascus steel out of (say) AEB-L and s90V, or wouldnt that gain the best of both? My test is for comparing different steels, not necessarily for a go/no go test for saltwater applications. 14C28N vs. D2. At the end of the article I gave a list of reasons why I hadnt made my own ratings chart, two big reasons were: 1) I didnt yet have articles explaining what edge retention and toughness even is (this was early on in Knife Steel Nerds), 2) I didnt have good experimental numbers on many steels. Anyway, astute comment, but edge retention does mean a lot in woodworking. you can easily buy a $500 knive made out of 14c28n, which has nothing in it besides cr and a trace of ni. Or even if they try to be more open to importance of toughness, the good reputation of the high edge retention steels means that they get inflated toughness ratings along with it. The ratings I have are for an optimal heat treatment. Between the assisted open, weird looking texture designs, and the stainless steel handle, the Cannonball has a lot of features I don't normally like, but even I have to admit it's a good design for the price. 12C27 steel is extremely popular in the US knife market for its high hardness, high wear resistance, and great corrosion resistance. However, many kinds of wood are REALLY tough and very hard on blades. A hunting knife has a singlepurpose: processing meat after akill. Marco, BSc Chem. imo o lot depends on how the blade is sharpened. There you said 7.6 for 420HC. By that I dont mean that a better heat treatment is not possible, but that major mistakes in heat treating are avoided. This does not predict which knife will cut longer or be more resistant to chipping. The steel is similar to Sandviks 13C26. This is a major tradeoff between improved cutting ability and edge retention with an acute angle vs a strong and chip resistant edge with an obtuse angle. But in use, Ive found nothing that withstands the abuse that 3V can take. Youre right I had to check my spreadsheet. This is good for ease in heat treating in large batches and for even cooling that greatly reduces warping and size changes. Moreover, the blades will serve you longer because they do not wear out faster with frequent use and sharpening. All of the experiments shown below are possible thanks to supporters. So youre right that a D2 blade will cut more CATRA cards than an AEB-L blade *when theyre both sharpened to the same angle* but AEB-L has much better toughness and can therefore handle being sharpened to a more acute angle without chipping, and a more acute angle is more important to continuing cutting ability than wear resistance is. In many cases the cost of working with the steel for the knife companies is more significant than the cost of the steel itself. https://knifesteelnerds.com/2020/05/01/testing-the-edge-retention-of-48-knife-steels/, Unfortunately it all comes down to marketing on everybody involved: Industry, knifemakers, users. This isnt exactly how steel works; different properties are difficult to increase without affecting something else. The knife does dull faster. it seems like all the pieces are in place to develop an algorithm for this. I have the average composition of the steels rated above (plus some extras) so you can see what the different names refer to. D2 is not a bad steel, but it has been around a long time and is somewhat mundane by current standards. European steel company Sandvik produces 14C28N, a non-powder metallurgy steel. Sorry, most of my previous comment was borderline word salad. Things are similar with resistance to chipping and edge deformation. 14C28N The consent submitted will only be used for data processing originating from this website. And a label: AEB-L. can you strike twice as fast with the knife? Im not sure they answer my question, though, and some of your points dont seem to jive with the info here on Larrins site. and get better and longer-lasting performance? It mainly made for knife and it high in Chromium for excellent corrosion resistance. Mostly it has been presented piecemeal with all of the studies that we have done on optimizing heat treatments of different steels like CPM-CruWear, AEB-L, 52100, etc. Tanto D2 steel Crucible intends SPY27 to be good all-around knife steel. 52100 and CruForgeV are good for general purpose knives. Steel is a combination of iron and carbon with other elements. To reiterate the clearer part, I wonder if toughness increases faster than edge retention decreases as an edge gets thicker. (Some crazy folks clean their Swiss Army knivesin adishwasher. The reason is because sharpening and edge geometry will also greatly control properties. Without any confusion, you can purchase this set that has a slim, versatile, modified drip-point blade with good slicing capabilities. https://www.patreon.com/Knifesteelnerds, Click to share on Twitter (Opens in new window), Click to share on Facebook (Opens in new window). Thanks to powder metallurgy, youll find even better edge retention on the high end. Its very similar chemically to RWL 34 and ATS-34. You can see that 64 Rc AEB-L has both lower toughness and edge retention than 61 Rc MagnaCut, so I feel that in general you get a better sense of where the steels fit with a single point. As a result, there are no production knives with REX 121 steel, though Ferrum Forge used the steel early on in its custom knives and a Kickstarter knife from the Creely Brothers.
