14c28n steel vs d2 14c28n steel vs d2

However, to choose the best knife for you must consider all the properties, including toughness, edge retention, corrosion resistance, and ease of sharpening. The pictures below show the microstructures of the three classes of stainless steel on the market. I havent tested Sleipner yet. does 1.4116 deserve the title of title of ultimate trash steel? However, even in this case there is the complicating factor of carbide and abrasive hardness. Many custom makers enjoy AEB-L, as its easy to machine but still has a high hardness, around 62 HRc. Micarta The only thing putting me off immediately buying the p135 is the 14c28n steel. I have an article that lists off the major mistakes often made in heat treating. just recently the idea occured tome to sharpen a planer blade like a knife and check out how it performs. It confirms what I always suspected and what anyone could have figured out by reading the technical data. . European steel company Sandvik produces 14C28N, a non-powder metallurgy steel. It mainly made for knife and it high in Chromium for excellent corrosion resistance. Even premium steels can have poor performance with poor heat treatment. Time and use have proven this to be quite accurate. Thanks to Bill Smutz, Alex Topfer, Florian Bachler, Brunhard, Art, Rod H, Sach, Jinny Koh, Jon Duda, Cory Henderson, and UPKnife for becoming Knife Steeel Nerds Patreon supporters! My other knives are a Real Steel E77 8cr14mov. If you want to learn more about a specific steel, you can click it in the sorted listings below. In this article, we will discuss the characteristics, pros, cons, and differences between 14C28N and D2 knives to help to make the right choice. If you have a favorite steel, rock on! [Steel Knife Review], What is 14c28n steel? Or, is this perhaps a historically useful practice that made sense on softer/less tough steels, but would make less sense on some newer steels that can be used at higher hardness and thus higher edge stability? What would you rate the toughness of CPM-D2. But it doesnt have great wear resistance and thus doesnt hold an edge particularly well. the problem is in the innumerable combinations of grades, grains sizes and coatings available. It also improves edge retention and strength. Hes already done a three part series on cryogenic treatment: The excellent corrosion resistance properties of 14C28N are attributed to the high amounts of chromium in its composition. Ive not seen these used on non-kitchen knives, though, and it seems that if they had real utility they would be used in other knives as well although perhaps on the thinner edges of kitchen knives they are more effective than they would be elsewhere? The studies confirmed that the primary controlling factors are hardness of the steel, volume of carbides, and hardness of the carbides. D2 steel is more durable than 14C28N, but it scores lower in terms of ease of sharpening and corrosion resistance. I did a test with knives in 440A (stainless), D2 (high alloy steel with some corrosion resistance), and 1095 (no corrosion resistance). Its very hard, tough, and corrosion-resistant. I have two quick questions, Hello everyone I've been loking into twosun knives recently. Rex 121 23.5% vanadium carbide, 4% molybdenum/tungsten carbide (M6C), Conventional Ingot vs Powder Metallurgy Carbide Structure. Like 154CM, its a good compromise between all three steel attributes. I measured corrosion resistance of a slightly lower carbon 420 here: https://knifesteelnerds.com/2020/03/02/cpm-spy27-experiments-toughness-corrosion-resistance-and-more/. If thats true why do you include it in the stainless steel category? 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. Steel with high wear resistance is more costly to manufacture, as the knife company goes through more abrasives to grind the knives. In other words, heat treating a steel to its maximum hardness does not necessarily mean reduced corrosion resistance. Most of the discussion of how the ratings were generated, various caveats and details, etc. The ultra high corrosion resistance steels Vanax or LC200N max out around 60-61 Rc instead. You can read more about these factors in my book Knife Engineering. Is this at the same hardness? Most steels use carbon to increase hardness, but 14C28N uses nitrogen, boosting hardness without the normal penalty of increased corrosion. 1. CPM 10V It has enough water-fighting properties that it can be used in marine environments. It can build a knife that sustains a sharp cutting edge for long periods and is sufficiently wear-resistant. 2) you do not go into the sharpening in much detail. LC200N Editors note: This article was first published in May 2015 and was most recently updated on May 25, 2020. The edge retention numbers are normalized to the hardness of the closest toughness test. 14C28N is the highest-selling steel of Sandvik, a Swedish steel company. The ratings I have are for an optimal heat treatment. 14C28N Vs D2 . It would be great if you wrote a basic rundown of cryo treatment of knife steels, whats involved, the effects, interactions with other treatments like tempers, alloys that benefit the most, etc. 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. Divers, sailors, and anglers need knives that will resist corrosion above all else. Damascus or pattern welded steel is a result of combining two steels together. However, Kershaw asked Sandvik to make their 13C26 steel more resistant to corrosion, and the result was 14C28N. I am particularly interested in researching knife steel, knife properties, and brands. I have a (relatively) short introduction before getting into the ratings with a few important things to put them into context. 1. Ease of Sharpening: One advantage of 8Cr13MoV is that it is easier to sharpen than D2 steel. 1.4116 G10 Everyone has their own opinion on what they deem the best folding EDC knife. H1 and 420 also have excellent corrosion resistance but are limited to lower hardness and edge retention. 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. Its called memory metal because heat can get it to revert back to a previous shape. Theyre excellent for choppers, hard-use folders, and outdoor knives that see impacts and heavy use when used at medium hardness. Id think that line would be significantly to the left, more in the data swarm. It is a Sandvik stainless steel that originally developed for razor blades. Let the job at hand be your guide. VG-10 steel also has the same level of toughness as 14C28N and the same level of corrosion resistance. Crucible intends SPY27 to be good all-around knife steel. The difference in properties between 14C28N and D2 steel is very clear. LC200N is produced with a special technique to add high nitrogen, giving steel excellent corrosion resistance on the top! Most of these steels rely on particle metallurgy and are therefore more expensive. Is there a reason SG2/R2 are not included in the lineup, despite being one of the most popular ones? There is buzz out there but I havent seen anything solid yet in the world of steel. 12C27 steel is extremely popular in the US knife market for its high hardness, high wear resistance, and great corrosion resistance. Ive found that most makers harden S30V too much, making it prone to chipping at the edge. Each test is done with 3 or more specimens to get a good average. What makes 1.4116 such a bad performer in regards to toughness on par with ultra high carbide steel like S125V? i understand the samples were treated in the same way. Its not bad, but you can find better in the market at the same price. When the blade gets messed up I just replace it. at least it has some vanadium over the 420hc. Oftentimes steels that are reported to be difficult to sharpen are in fact improperly heat treated and challenging to deburr. 8Cr13MoV still has some corrosion resistance, but not as much as D2. If you shop for knives based strictly on steel, you might be disappointed. D2 has been around for more than 20 years, an eternity in. 14C28N steel is known to offer the highest toughness levels out there. Great for tensile strength and Edge retention. If the steel is overheated in austenitizing, very large reductions in toughness are possible. drop point A good quality knife must have sharpness, great edge retention, and a sturdy handle. A2 Knife Steel Air-hardened tool steel. 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/. The consent submitted will only be used for data processing originating from this website. I actually dont recommend that enthusiasts spend all that much time analyzing the exact composition of different steels and trying to guess their properties. 14C28N I reserve the right to change my ratings based on new information. Not to sound like a ship, but these two knife inspiration makes this an eye-catching knife. The biggest change that is seen with powder metallurgy in measured properties is in regards to toughness. Though the volume of carbonitrides in the steel is relatively high. You can read about my CATRA edge retention testing in this article. If youre having trouble finding the steel you want, see if another manufacturer makes something much like it. D2 steel also offers similar toughness levels as the 14c28n steel, so both aren't really prone to chipping with proper use. With conventional steels this limited vanadium additions to about 4-5%, and this was greatly expanded when powder metallurgy was developed. This is a non-powder steel produced by American steel company Carpenter. On the other hand small but mighty, the pocket knife provides both in professional performance and in arresting good looks. In particular, I have found the ESEE/Rowen 1095 to be less likely to chip and better at holding an edge than the KA-BAR version even in knives with the same role, thickness, and blade length. So the major tradeoff is in how much carbide you want in the steel for edge retention without dropping toughness too much for the intended knife and user. This steel is quite corrosion resistant and sharpens easily. Get for a complete guide about other steel; you can read 14c28n vs 8cr13mov reviews. first there might have been some annealing going on (even if its was a microscopic level) and the steels might have reacted differently. Also known as Z-Finit, Zapp produces this steel in America. And for high toughness you want little or no carbide. I know it's much more stainless and corrosion resisitance, but what about wear resistance? So presumably, wear resistance would be in the 3.5-4 range and toughness in the 5.5-6 range. I forgot, I got the higher carbon steels will have higher edge retention from this website. Because of their good edge retention, these steels are quite versatile in folders and fixed blades. Yes its very easy to sharpen but it doesnt hold an edge at all. I was thinking maybe Sleipner or A2 would be best if a PM steel was out. And while it can be hard depending on the heat treat, I have found it easily chips, causing microscopic dings in the edge when hardened to a high level on a thin blade. Thats a tiny difference, but in combination with the 420HC disparity, it conceals a full point difference between 420HC and 440A: 7.6 vs. 8.6. A Japanese powder steel, ZDP-189 is essentially the polar opposite of 3V its uber-hard instead of uber-tough. 2. We and our partners use cookies to Store and/or access information on a device. How could it be? and yet millons of knives are being made out of 1.4116 (aisi 420mov?) The solid lockup and decent blade design make these two knives well suited for camping. But if you want to know what the coolest blade material is, for my money, SM100is it. Ruike Sandvik 14c28n vs D2 looking at getting a nice larger flipper for a little under 100 AUD. https://knifesteelnerds.com/2018/12/03/cryogenic-part1/ There has been some internet controversy over the grinding and heat treat of this steel. a burr might have developped on some of the steels and not on others, it might have ben reduced or even removed by the process. But a few overly vocal forgers were making claims about it that clearly were not true especially when comparing it to 5160. and get better and longer-lasting performance? Many steel ratings articles pay lip service to the importance of heat treatment without providing examples. HA! However, D2 steel has better edge retention, while 14C28N offers a better sharpening experience. I guess the question is whether toughness increases faster than edge retention decreases. 12C27 Hi there, Why do you give a coin with a knife as a gift? Most of the user loves this one that has received a lot of attention on this site. D2 is a tool steel used in industrial settings. Ah ok that wasnt mentioned. Because of the material difference, the blades differ in toughness, edge retention, corrosion resistance, and ease of sharpening. Spyderco and Cold Steel have used it, though Cold Steel recently switched to S35VN due to availability concerns. Recommendations are welcome, If you are cutting against metal I would maybe try K390 in a Spyderco or an S110V knife if you need stainless. Anyway, buff up the O1v and it cuts leather easily. To reiterate the clearer part, I wonder if toughness increases faster than edge retention decreases as an edge gets thicker. On the other hand, Speed safe assisted opening allows for easy blade deployment with the use of a simple pull back on the ambidextrous flipper.
