Here, we will discuss edge retention, toughness, ease of sharpening, and corrosion resistance. and why would anyone want to use it when 420HC looks so much better for a simple stainless steel option. Lots of information is still specific to this article, however. High toughness steels can be produced without powder metallurgy and also have low wear resistance for lower manufacturing costs. Hello LARRIN, do you have a Rough estimate on when ApexUltra (as well as more Magnacut) will become available? The main downside is the steel is more difficult to heat treat and can't go harder than about 60 or perhaps 61 Rc. Vg10 and cpms45vn same toughness at same hardness ? Im a layman trying to understand what makes the best steel for my use. AR-RPM9 Instead, Vargo titanium uses a unique material called sintered titanium-ceramic alloy. AEB-L and 14C28N are the best in the high toughness group. For these reasons D2 steel is a good for smaller folding knives, but is not ideal for large fixed blades such as dedicated choppers and large survival knives. I wrote an article about knife steel ratings available online in 2018, where I concluded that none of them were very good. 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/. Ive found S35VN less chippy even at the same hardness. 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. The vivid patterns visible in Damascus steel come from the acid etching process in a ferric chloride solution. It does have chromium but is not as sufficient as required to be a type of stainless steel. blue steel while its a very intuitive method and a simple way to e.g. 14C28N steel holds good hardness. 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. 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. Sorry, most of my previous comment was borderline word salad. While quite soft, the metal cuts even when it seems dull because, at the microscopic level, it has a roughness that performs much like a serration. [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. Read about my tests in this article. What would be the best deal to use I currently alternate between 20CV S35vn and D2. Jesse Jarosz, a custom maker from Montana, regularly uses AEB-L. Most of the user loves this one that has received a lot of attention on this site. D2 steel does not contain enough chromium to make it stainless steel. Thanks to powder metallurgy, youll find even better edge retention on the high end. CPM-S90V is my favorite in the high edge retention category because of its decent toughness. The line is only in the neighborhood of 5 of the datapoints. D2 steel also resists chipping better than most stainless steel types. 14C28N VS D2 The two sheets of steel are comparable in terms of toughness and corrosion resistance. 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. But in my experience, it has been nothing but great. imo o lot depends on how the blade is sharpened. Im going to give the ratings first and then give more explanation about how the ratings were created. Note that corrosion is detrimental for the cutting edge. Actually, Id be thinking 14C28N, but I want to leave stainless out. This is to keep the focus on the elements that are making the biggest difference. 14C28N and D2 steel are not the same. 14C28N is a type of high-performance stainless steel used in knife-making. 8Cr13MoV still has some corrosion resistance, but not as much as D2. Though the volume of carbonitrides in the steel is relatively high. Coarse-carbide tool steel grades. In many cases, the D2 edge sharpness may last a bit longer. Oftentimes steels that are reported to be difficult to sharpen are in fact improperly heat treated and challenging to deburr. The sharpening makes the knives easy to maintain because they dull faster and require frequent sharpening. second it might be of importance which way you sharpened because if against the edge the steels might have reacted differently to the contamination remaining on the edge. Note:Dont bother with anything less than 8Cr in this series. 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. This was not necessarily because of superior toughness but because of the superior strength of the MagnaCut from higher hardness. It would be really useful to have the raw data that backs the charts that you produce. 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. LC200N has similar properties to those two but with saltwater levels of corrosion resistance. If you look at the chart you may notice that at high toughness levels if you increase edge retention by only a relatively small amount you get very big drops in toughness. 12C27 steel is extremely popular in the US knife market for its high hardness, high wear resistance, and great corrosion resistance. 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. Wear resistance comes from hardness and carbides, hard particles formed between carbon and another element like Vanadium or Tungsten. 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. The old rule in steels used to be corrosion resistance, toughness, or hardness choose two. But SM100 (the trade name for Nitinol 60) threw that out the window when introduced to the cutlery world. Im not hating on 80crv2 , Ive used it. A lot of custom makers also like S110V, including the great RJ Martin. On the other hand small but mighty, the pocket knife provides both in professional performance and in arresting good looks. The steel was developed to be free from chromium carbides which gives it properties similar to balanced non-stainless tool steels like CPM-4V and CPM-CruWear. There are significant differences between them because 14C28N is stainless steel, while D2 steel is a semi-stainless tool steel. 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). It is among the best steel that will offer exceptional toughness while still maintaining excellent corrosion resistance. The blackwashed D2 steel blade of the Kershaw Cannonball offers pretty good corrosion resistance for D2. Then you can compare 14c28n vs d2, and we hope you will find the right one for your needs. Its actually quite good, low-cost steel that performs like midprice steel. With toughness it is a bit harder to link to only one article as I dont really have a summary of all of the toughness testing that we have done. Here, youll learn the different factors that go into each steel, ratings for a wide variety of steel alloys, and youll get some recommendations for types of knives different types of steel work well for. We use a subsize, unnotched chapy test with 2.5 x 10 x 55 mm dimensions. Three main characteristics differentiate steels from one another: corrosion resistance, hardness, and toughness. AEB-L and 14C28N also have moderate edge retention though of course much lower than vanadium-alloyed powder metallurgy steels like S30V or M390. 14c28n is the most popular material for the knife: stainless steel and made by the Swedish company. The most traditional models of pocket knives have different parts, such as the handle and cutting performance. You can read more about these factors in my book Knife Engineering. There one of the best reason that he is highly regarded as a knife designer. 12C27 The Kershaw Leek is a most popular EDC knife that design by legendary custom knife maker Ken Onion. . Great for tensile strength and Edge retention. 14C28N steel, also known as Sandvik 14C28N, is stainless steel made by Sandvik, a European steel company in Sweden. D2 steel is high carbon steel with no extra addition of Cr or Mo, that's why it is prone to corrosion. 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 10V specimens tempered at 1000F were 4-5 ft-lbs while the specimens tempered at 4-500F were 7-8 ft-lbs. Only a skilled blacksmith can make Damascus steels, so they tend to be expensive. D2 steel offers better edge retention and wear resistance than 14C28N. Most of these steels rely on particle metallurgy and are therefore more expensive. The most balanced is CPM-MagnaCut which is in an area all by itself on the chart. The only thing putting me off immediately buying the p135 is the 14c28n steel. Why does Maxamet and Rex 121 stay the same tcc but Zmax drops and 15v goes from below 900 to over? vanax Dr. Thomas is a friend of ours here at Blade HQ, and with his help, weve worked to create this knife steel guide. The value being slightly different doesnt mean its an outlier or measurement error. This is about comparing steels to each other rather than a limitation of an individual steel. 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? We have our views as well, and here they are! Also D2 is not stainless as at least 5% of its chromium is tied up in carbides where it doesnt help prevent corrosion. This is especially important for chopping knives and for knives with thin edges for enhanced cutting ability and edge retention. 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? PESR would be an interesting topic too (also tied to LC200N). It richly deserves its reputation for high-quality gained over the years by Sandvik, a Swedish manufacturer of world-renowned steel. In use, its very similar to 440C and VG-10. But a few overly vocal forgers were making claims about it that clearly were not true especially when comparing it to 5160. Its soft, with very low carbon content. Ah ok that wasnt mentioned. 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. Distilled water can separate steels that are stainless vs those that are not. How do its properties compare to other steels? Is it similar but worse or better at one of the 3 things? The most significant cost increase comes from powder metallurgy, used to create most of the expensive knife steels. In other words, heat treating a steel to its maximum hardness does not necessarily mean reduced corrosion resistance. I have a Spyderco K390 knife and I cut leather with it as it is only .090 thick and I seldom have to strop it on 1 micron diamond compound on leather. Many steel ratings seem to over-emphasize edge retention. Five years ago, S30V had a premium price. LC200N is produced with a special technique to add high nitrogen, giving steel excellent corrosion resistance on the top! and yet millons of knives are being made out of 1.4116 (aisi 420mov?) Read more about how it works here. It was your original article on ratings that brought me to knifesteel nerds so its great to see your results put back into a form that will no doubt be distributed \ plagiarized widely, hopefully leading to more rational thought and better understanding by the knife consuming public (not that the misleading marketing will go away). Edge retention often refers to the ability of a knifes edge to maintain its sharpness during use. in relation to hardness). 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. ZDP-189 can tarnish, though not as easily as 3V. . The highest edge retention steel was Rex 121 which was at 70 Rc in combination with lots of high hardness vanadium carbides. Its OK to be a steel snob, but keep in mind that you dont have to if you want a good knife. Still looking forward to magnacut making it into high volume production and use. Socould you please clarify which steel is the outlier and which is the line>. The choice between the two depends on your knife needs. Required fields are marked *. The solid lockup and decent blade design make these two knives well suited for camping. Should you continue to scroll further, you may find yourself lost in a seemingly endless list of knife steel wealth and knowledge. Vanadium carbides are very large with conventional production of steels but are very small with powder metallurgy. If you are a newbie, sharpening D2 knives will be a struggle, but it is doable with practice and the right sharpening tools. I do not have rust issues with it (as long as I have a good finish) some heavy stonewashed finishes rust easier. The only thing putting me off immediately buying the p135 is the 14c28n steel. edge retention can vary by several orders of magnitude depending on what happens to the burr. . Its a very hard steel and is exceptionally difficult to sharpen. Chris Reeves version, which is about two points less hard than others, is quite good. No mainstream companies use SM100, and the niche makers that do usually charge more than $1,000 for knives with SM100 blades. 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. 420HC doesnt hold an edge well, but its relatively stain-resistant and tough. The ESEE had significant edge damage while the MagnaCut knife did not. I have not provided a rating for ease in sharpening. Reddit and its partners use cookies and similar technologies to provide you with a better experience. 14C28N steel is as a result of a more corrosion resistant version of the 13C26 steel. Hi Larrin, thanks so much for writing this blog and putting so much reliable information into such an accessible form. S45VN 1095 stains easily and thus is often coated, especially in fixed blades. https://cedric-ada-store.creator-spring.com/listing/brickard-heritage-collectionGood gravy its bricky on thingsSubscribe and hit the bell!
