Its exceedingly tough and relatively hard, but its not stainless. This guide explains important features to consider when buying a new knife for the outdoors. Some of these steels also have vanadium (CruForgeV) or tungsten (Blue Super, V-Toku2, 1.2519) for increased wear resistance. . Advantages: Toughness, edge retention. we dont know. Id like to quote some of your toughness, edge retention and corrosion resistance for balanced midfield steels, including yours, in some data tables. great work, larrin. These images are taken from my book Knife Engineering. Obviously Ill let you check the manuscript prior to publication. I like it. https://www.patreon.com/Knifesteelnerds, Click to share on Twitter (Opens in new window), Click to share on Facebook (Opens in new window). The 8Cr13MoV vs D2 debate. The critical difference between these two sheets of steel is their corrosion resistance. This is a very important factor when selecting a steel for your knife blade, especially if you plan on spending a lot of time outdoors in an area with high humidity.. S30v is a higher ranked steel and considered a true Stainless Steel, with a 14% . It doesnt hold an edge well, but its so easy to sharpen that you can get it back to razor sharpness in a few minutes. I was wondering if the 14c28n sample was also prequenched like the AEB-L toughness samples? A Japanese powder steel, ZDP-189 is essentially the polar opposite of 3V its uber-hard instead of uber-tough. 14C28N VS Steel. You can see micrographs of different knife steels to compare their carbides in this article. You do not expect the prices to be as low as those of low-end knives, but you will get high performance at affordable prices with either. Display: 24 per page Sort by: Featured View CIVIVI Voltaic Flipper Knife Stainless Steel Handle With Micarta Inlay (3.48" 14C28N Blade) $88.30 Add to cart AR-RPM9 Hello everyone I've been loking into twosun knives recently. For high wear resistance and edge retention you want a large amount of hard carbides. The biggest change that is seen with powder metallurgy in measured properties is in regards to toughness. nevertheles its importand to keep in mind what exactly is going on there (abrasive plastic media, loss of most of cutting ability during the first few strokes etc.). Because of its difficulty in sharpening and machining, its very rarely used and comes with a high price premium. These steels are best for knives that dont see impacts and are some of the most difficult to sharpen. One of the more common stainless steels, and one readily available in lots of different places worldwide, AUS-8 is a decent all-around steel. 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. You can read more about these factors in my book Knife Engineering. Another common heat treating choice that is not even categorized as a mistake is tempering in the high temperature regime (~1000F) rather than the low temperature regime (~400F). However, this edge retention comes at the cost of sharpening ease for D2. Developed by New Jersey Steel Baron, Nitro V is a non-powder steel marketed as an enhanced version of AEB-L. Nitro V, as its name indicates, adds nitrogen to AEB-Ls formula to make the steel even more corrosion-resistant. 7:00am-5:00pm, 10am-7pm Tuesday - Friday https://knifesteelnerds.com/2018/12/17/cryogenic-processing-of-steel-part-3/. 14C28N is the highest-selling steel of Sandvik, a Swedish steel company. Theres also a line of green triangles a bit below that. I know it's much more stainless and corrosion resisitance, but what about wear resistance? All rights reserved. then you have zirconia and diamond coated blades. CPM154 is a truly superior steel. 2. The majority of knives target 63 Rc or below so this limitation of stainless steels does not always come into play but can be an important factor for certain knives targeting high performance and thin edges. Both knives come at an affordable price for high-end knives. They made planer blades out D2 for its edge retention. also the angle is by far the most important factor in catra testing, so such results might be irrelevant. There has been some internet controversy over the grinding and heat treat of this steel. For more information, please see our Note that corrosion is detrimental for the cutting edge. While 9Cr18MoV steel is highly corrosion resistant due to the addition of Cr, and Mo. Another important caveat before we get to the ratings are that these are for the steel only. https://i0.wp.com/knifesteelnerds.com/wp-content/uploads/2021/10/stainless-toughness-10-19-21.jpg?w=757&ssl=1 Marco, BSc Chem. 14c28n vs. D2 Steel D2 is as rigid as 14c28n, thus has almost equal edge retention abilities. It also improves edge retention and strength. 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. Because of its abrasion-eating hardness, knives with REX 121 come at an exceptionally high price. It is a premium steel that is known for its excellent balance of hardness, corrosion resistance, and edge retention. The most significant cost increase comes from powder metallurgy, used to create most of the expensive knife steels. 14C28N VS D2 Attributes: 14c28n: D2 . And only Vanax and LC200N have been free from corrosion with a 3.5% saltwater solution, though MagnaCut was close. They are usually chosen for their looks rather than performance. Can you contact me via my email address so I can send you a copy in PDF and epub. Tough steel can handle impacts without gross chipping or a tip breaking off. Hi Jimmie, thanks for your comments. That comes with an excellent return of experience that makes it ideal for the manufacturer of outdoor and tactical knife blades. Copper frame are very sturdy and machine well and take the best patina over time. But its lightyears ahead of the alternatives, specifically titanium-bladed knives. Both steels are popular among knife manufacturers and both have their strengths and weaknesses. . If you need something that soaks up abuse, try 3V. Im not sure they answer my question, though, and some of your points dont seem to jive with the info here on Larrins site. [Steel Knife Review], What is 14c28n steel? The hardness of the carbides does not matter much unlike with edge retention. https://knifesteelnerds.com/2018/12/03/cryogenic-part1/ However, there are other factors. D2 is not a bad steel, but it has been around a long time and is somewhat mundane by current standards. Short of purposeful abuse, its all but impossible to chip an edge on an INFI blade. They differ little in composition and treatment. 14C28N steel is the improved version of 13C26 with better rust resistance. Less expensive, conventionally produced steels include VG-10, D2, 154CM, N690, and 440C. 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). But a few overly vocal forgers were making claims about it that clearly were not true especially when comparing it to 5160. 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. Read more. Anyway, astute comment, but edge retention does mean a lot in woodworking. Ease of Sharpening: One advantage of 8Cr13MoV is that it is easier to sharpen than D2 steel. The unique process used to make LC 200N results in a fine-grain structure. 52100 and CruForgeV are good for general purpose knives. Deburring of edges often takes even longer than removing material to produce the edge. Combination of knife steel properties. Corrosion is not only cosmetic. Even premium steels can have poor performance with poor heat treatment. With a high level ofedge retention, corrosion resistance, and toughness, it does most everything quite well. Spyderco is the only production company using this steel, though Michael Gavik of Gavko knives produced a number of customs in LC 200N. An example of data being processed may be a unique identifier stored in a cookie. Corrosion on knife steels most usually takes the form of rust, patina, and staining. I did a test with knives in 440A (stainless), D2 (high alloy steel with some corrosion resistance), and 1095 (no corrosion resistance). False treatment and geometry upheld by Made in USA is like buying 8Cr from China (except late A.G) My personal experience tops with Vanadis 4E, CPM-M4, RWL-34 and the likes. I also have meat cleaver 1,4116 ,58RC that I order and was looking up if its a good steel or did waist money and need to return it. the following is not a critique, just a few thoughts to maybe put the relationships into a wider perspective and point to additional dimensions. 3) catra is (as far as i know) the only accredited (iso/en) testing method. And steels with at least 10% chromium are probably stainless, except for several important exceptions like D2 and ZDP-189. Are you okay with that? Contact me if you have any questions or input! It rusts like nothing Ive seen before and it dull just by looking at it. Im going to give the ratings first and then give more explanation about how the ratings were created. S90V Did you change the estimate based on more testing? there seems to be an optimal procedure for every alloy (provided its heat treated to industial standards). 1060 In use, its very similar to 440C and VG-10. Distilled water can separate steels that are stainless vs those that are not. The most balanced is CPM-MagnaCut which is in an area all by itself on the chart. I love reading through all the data youve gathered and making note of all the trends (Im a physical organic chemist). HAP40 The steel comes with increased wear and abrasion resistance properties. In general, higher carbon and higher vanadium steels have higher wear resistance and edge retention but lower toughness. GiantMouse Vox/Anso ACE Iona Liner Lock Knife, Muley Freaks Erik Van Woerkom Charged With Felony Possession of Trophy Mule Deer, The Biggest Improvement to My Camp Kitchen Is a Mini Pizza Oven (But Not for Pizza), Propane Traeger, Moosejaw Coolers, Hybrid HOKAs, Adventure Chess, and More Emerging Gear, Avalanche Outside British Columbia Resort Buries 10, Kills 3 Heli-Skiers, Netflix Unveils First Trailer for Tour de France Series. Also D2 is not stainless as at least 5% of its chromium is tied up in carbides where it doesnt help prevent corrosion. I believe they are made of simple carbon steel. Would love to see where S7 sits on the Corrosion/Edge/Toughness meter. You cant look at only the chromium content of the steel to know the level of corrosion resistance. While not a powder steel, 154CM is widely used in nicer knives. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. Thats a pretty large difference in two budget steels that are often compared to each other. It has a lower hardness and edge retention as compared to the 9Cr knife. The bump in hardness comes from precipitation of fine carbides in the steel, which include chromium carbides. The steel is similar to Sandviks 13C26. VG 10 Steel, https://knifebasics.com/author/freelancer/, How To Choose Between The 14C28N And The D2, 14c28n Steel Is Good for Knife? Stainless steels are another subset of high alloy tool steels that have enough chromium in them to have stainless levels of corrosion resistance. Ive seen more talk and some articles regarding the use of AI to come up with new potential drug molecules, polymeric materials, etc. Here, read on for an in-depth look at common knife steels as well as the best knife steels around. These two knives are a little bit more than a pretty face. imo o lot depends on how the blade is sharpened. There are still a few things I dont know but we have enough information to make educated guesses where data isnt available. Its hard to imagine a more rust-inducing environment than saltwater and fish guts. A2 knives need care taken to avoid rust and are often coated to inhibit corrosion. But in my experience, it has been nothing but great. Read more. 14C28N is thus ideal for use in corrosive environments and challenging applications. worldwide, even the chinese have an equivalent (8cr13mov). There is no such thing as a steel that is a 10 in both toughness and edge retention. Even it enhances corrosion resistance and wear resistance. 14C28N Below shows the results of MagnaCut testing vs other steels where it is labeled as New Steel.. I have not provided a rating for ease in sharpening. But in use, Ive found nothing that withstands the abuse that 3V can take. Used in knives since at least World War II, 1095 performance varies considerably with an abundance of tweaks in the recipe and heat treat. Its actually quite good, low-cost steel that performs like midprice steel. You said wood is not a particularly abrasive material and in absolute terms that is very true. ), intended use will give you all the answers. Even metallurgists can have a difficult time estimating properties just based on the elements. 1% saltwater will separate between other stainless steels. This is an old high-carbon (non-stainless) steel. Its in the same class as Vanadis 8 and 10V. This is one of the fundamental tradeoffs in steel. i understand the samples were treated in the same way. I was the heat treater, but after HT to only 58-59 hardness the blades went to the surface grinders for finishing and I remember them going into the packing boxes with mirror polished edges. Many steel ratings seem to over-emphasize edge retention. Read more. Thanks! Jeff I worked at a company that heat treated D2 (1.55% C) planer blades for a company that built wood working equipment for commercial shops. I cant seem to match steel to the SS data points on the toughness/tcc graph. H1 and 420 also have excellent corrosion resistance but are limited to lower hardness and edge retention. Low Carbon steels like AEB-L wont hold up to wood cutting even though it can hit 64 hard, it just doesnt have enough Carbon.. Honestly, yes, because its perfect steel for your knife, besides it depends on which knife, so when youre talking about chef knives, then 14c28n would be an ideal pick thanks to professional corrosion resistance and edge retention. It would be interesting to try to develop a conversation between /geometry/edge retention/toughness, so we could say e.g. It will take you more time and energy to get a sharp edge, but your efforts will pay off because the blades hold the edge longer. In reality hardly difference. As such, the performance of the steel is entirely dependent upon the steels being utilized. I would like to see the rating and performance on test of the Chinese Steels, that some people use to say its cheap garbage, like 3Cr13MoV, 4Cr13, 4Cr13Mo, 4Cr14MoV, 5Cr15MoV, 6Cr13MoV, 7Cr17MoV, 8Cr13MoV, 9Cr13MoVCo, 9Cr18MoV, 9Cr19MoV, and the 14cr14MovNB to see if they are similar, worse or better than the steels that they copyi believe we gonna have some good unexpected results. It's like the difference between average 420HC and Buck's 420HC with the Bos heat treatment, only from a better starting point. YMMV I tested its edge wear resistance but not its toughness yet. For instance, if a 35 edge in 1095 steel at 58 Rc provides appropriate toughness for planing hardwood, what edge angle in, say, AEB-L at 62 Rc might give us a comparable effective toughness? This refers to the angle of your edge and the thickness of the knife behind the edge. A good quality knife must have sharpness, great edge retention, and a sturdy handle. Its easy to sharpen. The table shows combinations of knife steel properties for different classes of steel. Though technically not a stainless steel at least 14% chromium, and D2 usually has 12% its relatively corrosion-resistant. Aluminum oxide is used in most common sharpening stones and it is softer than vanadium carbide, which makes sharpening high vanadium steels more difficult. 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? Goes to show that science not marketing or conjecture is what determines a good steel, 51shitty? In a pocket knife the total amount of steel is rather small. 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. Steels like CPM MagnaCut, CPM M4, CPM 4V, and CPM CruWear fit in this category. Because of their good edge retention, these steels are quite versatile in folders and fixed blades. SPY27 On the other hand, 9cr18mov has a slightly higher molybdenum content which gives it higher hardness from quenching and helps drive carbide formation. ApexUltra is a steel that we are working on that had excellent properties in small batch production (50 lbs). I wrote an article about knife steel ratings available online in 2018, where I concluded that none of them were very good. The excellent corrosion resistance properties of 14C28N are attributed to the high amounts of chromium in its composition. The knives can be used in humid and wet environments without rusting. CPM-REX 121 and Maxamet are both in this category. Edge retention is the ability of a knife to maintain cutting ability during cutting. CTS-204P and CPM-20CV are nearly identical steels made by other manufacturers. Vanax gives up some toughness and hardness vs MagnaCut for saltwater levels of corrosion resistance. It is a Sandvik stainless steel that originally developed for razor blades. D2 has been around for more than 20 years, an eternity in metallurgy terms. And below shows a chart of carbide hardness, the equation we created to predict edge retention based on edge angle, hardness, and carbide volumes, and then the chart showing the good correlation: TCC (mm) = -157 + 15.8*Hardness (Rc) 17.8*EdgeAngle() + 11.2*CrC(%) + 14.6*CrVC(%) + 26.2*MC(%) + 9.5*M6C(%) + 20.9*MN(%) + 19.4*CrN(%). While some are into that type of thing, if youre familiar with a specific steel and want to compare it with another, you should definitely click on that button below. H1 Not impractical fantasy knives, but these two knives that have a col look to them. 14C28N steel is known to offer the highest toughness levels out there. Steels that can be high in edge retention and toughness are desirable for general use knives. I would suggest adding a second axis to the ratings charts that show the data values that the 0-10 ratings are based on (unnotched charpy impact energy, 1% saltwater , Total cards cut, etc.). 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. Generally seen as a slight upgrade to the 440C/VG-10/ATS-34 caliber of steel, its a decent all-around steel with good corrosion resistance, decent toughness, and only modest hardness. Everything you need to know to buy the right knife for the job. I also have a video that summarizes some of the information below while also showing how some of the experiments work. . Also known as Z-Finit, Zapp produces this steel in America. However, it falls behind the Bohler steel in corrosion resistance. Here, we break down how to choose a flashlight, including best flashlight LEDs, batteries, designs, and more. Check out theGiantMouse Vox/Anso ACE Iona Liner Lock Knife at $99, for example. It applies to both of course, hence why there isnt a separate label. But the true calling card of INFI is its insane toughness. Spyderco and Cold Steel have used it, though Cold Steel recently switched to S35VN due to availability concerns. Kershaw, Spyderco and Schrade are among some of the popular users of this steel.. 14C28N. 14c28n is the most popular material for the knife: stainless steel and made by the Swedish company. D2 steel also offers similar toughness levels as the 14c28n steel, so both aren't really prone to chipping with proper use.
