Custom maker Brian Trudeau uses Nitro V, and Massdrops Perpetua design is the first production knife to sport it. Crucible intends SPY27 to be good all-around knife steel. Theyre excellent for choppers, hard-use folders, and outdoor knives that see impacts and heavy use when used at medium hardness. I reserve the right to change my ratings based on new information. 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. Each of these contributes to a knifes overall performance. I dipped each in lemon juice and left in open air and tested after 30, 100, and 300 minutes, dipping in lemon juice again each time. The chart below has dotted lines which indicate the average effect of hardness for any given steel. The steel is an air-hardness tool steel that is considered semi-stainless because of its high chromium content. In use, its very similar to 440C and VG-10. : 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). For this perfect size that for most tasks and the slim tip allows the knife to excel at piercing and detail work. D2 is a high carbon, high chromium die steel and is the highest carbon alloy tool and die steel typically used in knife making. Cool! S110V has improved corrosion resistance at the cost of some toughness compared to S90V. What it is: 14C28N is a Sandvik stainless steel commonly used in razors and kitchen knives. Due to its higher Chromium content, S30v is a lot less likely to corrode/rust than the D2 Steel. Sorry, most of my previous comment was borderline word salad. This is a powder steel produced by American steel company Carpenter. and our how much more can you bend/pry with it? 8Cr13MoV still has some corrosion resistance, but not as much as D2. In nitrogen steels, nitrogen is used as the iron-hardener instead of carbon, thus limiting the possibility of rusting. The very good toughness of MagnaCut meant that it didnt chip despite this relatively high hardness and the difficulty of the test. Rather than upgrade from D2 to M4 or S30V just drop the angle from 40 degrees to 30 degrees. Each test is done with 3 or more specimens to get a good average. 14C28N steel is not very hard steel which makes it easier to sharpen. 14c28n is the most popular material for the knife: stainless steel and made by the Swedish company. Or is this an argument that tends to be rooted more in the presumption that Japanese steel > Chinese steel than any practical difference in reality? D2 knives, on the other hand, are challenging to sharpen. Therefore, if your priority is a knife with the best toughness on the market, you can never go wrong with the varieties of 14C28N. Here its 8. Thanks for the Article Larrin, We looked at common steels used by popular knife brands to help you select the right material for your blade. It applies to both of course, hence why there isnt a separate label. It has excellent edge retention, corrosion resistance, and ease of sharpening. Corrosion is not just about cosmetics and rusting, however, but can also affect edge performance. 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. 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. One argument I see consistently leveled against 8Cr13MoV compared to AUS-8 is that of the consistency of the composition. Sure if you dont want stainless steel fine, but there are plenty other carbon steels out there much better than 5160. 1. Heres The Best Review For You (2021), D2 knife blade offers high edge retention, Dulls faster, Requires frequent sharpening. show very different and even inversed behaviour (e.g. Not as tough as the best carbon steels, it's tougher than most . We have our views as well, and here they are! LC 200N is an elite performer, with high hardness, high toughness, and off-the-charts corrosion resistance. 1060 We all have our preference, but overall, preference leans towards the pocket knife with a clip. Maxamets hardness results in incredible edge retention and a nightmarish sharpening and machining experience. 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. 14C28N steel is the improved version of 13C26 with better rust resistance. Toughness and edge retention are generally opposing properties and it is difficult to improve both of them at the same time. Is Vancron SuperClean a good choice for a chef knife? The Sandvik 14c28n steel is ideal for the manufacturing of steel knife blades. Vg10 and cpms45vn same toughness at same hardness ? Most of the user loves this one that has received a lot of attention on this site. 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. Where the black-finished 1.4116 version has a simple, full flat grind, the D2 version has a compound flat grind that ends halfway up the blade's height. On the other hand, in d2 air-hardness steel, you cant differentially temper the blade-like other high carbon steel because the steel can also be challenging to sharpen. So, its hard steel is easy to sharpen. worldwide, even the chinese have an equivalent (8cr13mov). D2 holds it for longer. I tested its edge wear resistance but not its toughness yet. The big difference in properties vs the low alloy steels, however, are the harder carbides that are found in these steels. In my experience, it will tarnish and discolor quickly. Would be great if some manufactures changed their steels based on this information. Like 154CM, there is a newer version, S35VN, which shares many of the same attributes as S30V but is easier to craft into a knife thanks to niobium. Though the volume of carbonitrides in the steel is relatively high. https://knifesteelnerds.com/2018/12/17/cryogenic-processing-of-steel-part-3/. LC200N With recommended hardness range of 55-62 HRC; the 14C28N is great for knife applications which place very high demands on edge sharpness, edge stability and corrosion resistance such as chefs knives, hunting knife, pocket knives and fishing knives. imo o lot depends on how the blade is sharpened. It confirms what I always suspected and what anyone could have figured out by reading the technical data. Fix-It Sticks Compact Ratcheting Multi-Tool Review, Toughness, Wear Resistance, Corrosion Resistance. This is a virtually stain-proof steel suitable for all sorts of aquatic environments. Some of these steels also have vanadium (CruForgeV) or tungsten (Blue Super, V-Toku2, 1.2519) for increased wear resistance. [Steel Knife Review], Best survival knife sword: 5160 steel Review, What is VG 10 pocket knife? The pictures below show the microstructures of the three classes of stainless steel on the market. After the steel is quenched it is reheated to a lower temperature to increase toughness and decrease hardness. 2) you do not go into the sharpening in much detail. Most vintage tool blades seem to have been made of 1084/1095 or similar, presumably at some <60 Rc hardness that gave the required toughness, and the rules of thumb for sharpening angles are based on those assumptions. As to a difference between 8.6 and 8.5, all of the ratings here are rounded to the nearest 0.5 because better than that probably shows false precision. A cryo treatment and close temperature control is necessary to achieve those hardness levels. Things are similar with resistance to chipping and edge deformation. Its very similar chemically to RWL 34 and ATS-34. Some steel companies charge more than others. D2 is another medium-range tool steel. On the other hand the professional performing blade steels sharpen to a razor edge and hold the edge for an extended use. Oftentimes steels that are reported to be difficult to sharpen are in fact improperly heat treated and challenging to deburr. If the steel is overheated in austenitizing, very large reductions in toughness are possible. 14C28N and D2 steel are not the same. These steels are best for knives that dont see impacts and are some of the most difficult to sharpen. The D2 version is heavier and harder, but doesn't cut as smoothly. The table shows combinations of knife steel properties for different classes of steel. That way you can get into the steel ratings quickly. Sign up to receive GearJunkie content direct to your inbox. European steel company Sandvik produces 14C28N, a non-powder metallurgy steel. Note:There is a powder-metal version called CPM154 thats purer than the non-powder version, making it easier for knifemakers to grind. Goes to show that science not marketing or conjecture is what determines a good steel, 51shitty? does 1.4116 deserve the title of title of ultimate trash steel? Contact me if you have any questions or input! REX 121 is a powder steel produced by Crucible. This is especially important for chopping knives and for knives with thin edges for enhanced cutting ability and edge retention. I did a test with knives in 440A (stainless), D2 (high alloy steel with some corrosion resistance), and 1095 (no corrosion resistance). However, high wear resistance means that abrasives are used up more rapidly, more careful grinding is necessary to avoid overheating, finishing and polishing is much more time consuming, etc. That provides 14% Chromium and offers excellent corrosion resistance. A hunting knife has a singlepurpose: processing meat after akill. If you are a newbie to steel knives and the differences are not yet clear, come with us to the next section as we look into each knifes characteristics, pros, and cons. Ease of Sharpening: One advantage of 8Cr13MoV is that it is easier to sharpen than D2 steel. Compared to the AUS10A, the D2 has a longer legacy since it's been around since 1918. There is no such thing as a steel that is a 10 in both toughness and edge retention. Ruike Sandvik 14c28n vs D2 looking at getting a nice larger flipper for a little under 100 AUD. Do honing steels as used on kitchen knives actually do anything useful? Ah ok that wasnt mentioned. There are significant differences between them because 14C28N is stainless steel, while D2 steel is a semi-stainless tool steel. 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. This guide explains important features to consider when buying a new knife for the outdoors. 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. But its very cheap, and, when ground appropriately, it can be a real winner from a value standpoint. There is no single category that means that a steel is more premium or better than another. Where did it come from? Because of its difficulty in sharpening and machining, its very rarely used and comes with a high price premium. I have not provided a rating for ease in sharpening. 3) catra is (as far as i know) the only accredited (iso/en) testing method. CRKT and Spyderco use BD1. This showed that XHP and ZDP-189 have significantly lower corrosion resistance than other stainless steels. D2 steel offers better edge retention and wear resistance than 14C28N. its like with cars, most of them are not a corvette or a porsche. The knife Natrix with substantial copper handle is a deceptively hefty EDC. I believe they are made of simple carbon steel. Tough steel can handle impacts without gross chipping or a tip breaking off. 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(%). Steels like CPM MagnaCut, CPM M4, CPM 4V, and CPM CruWear fit in this category. Hello LARRIN, do you have a Rough estimate on when ApexUltra (as well as more Magnacut) will become available? quite possibly the best steel youll find on a sub-$30 production knife. 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. Edge retention is the ability of a knife to maintain cutting ability during cutting. I feel like it sharpens as easy as D2. The bump in hardness comes from precipitation of fine carbides in the steel, which include chromium carbides. There are a lot of different types of steel out there . Thanks! While not a powder steel, 154CM is widely used in nicer knives. Almost all consumer-grade pocket knives, EDC knives, fixed blade knives, etc will be in the range of a Rockwell Hardness rating of 54 to 65 HRC. The studies confirmed that the primary controlling factors are hardness of the steel, volume of carbides, and hardness of the carbides. An example of data being processed may be a unique identifier stored in a cookie. But if when youre searching for tough steel for your outdoor experience camping, or hunting, it would be perfect steel but not the best choice therere other steels with better than toughness that would suit your usage. 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). are after the ratings. 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. CPM 10V This steel is quite corrosion resistant and sharpens easily. VG-1 is a non-powder steel made by Japanese specialty steelmaker Takefu. Steels 7Cr and below arent worth your time or money. 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. These steels are typically used by forging bladesmiths, traditional folders, and some production fixed blades. I couldnt find much on 5160 steel and from a knife makers point of view if you are saying youre the preferred supplier of special ops than I dont understand this choice in knife steel. This particular steel grade allows for the highest attainable hardness without. Damascus or pattern welded steel is a result of combining two steels together. The steel loses some of the chromium in solution for corrosion resistance to form these fine carbides for hardness. 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. https://knifesteelnerds.com/2018/12/03/cryogenic-part1/ This is an American-made powder steel. I just want to thank you for all the work you do for the community and the world at large. If you want to check the quality of my work, just search for The EDC Bible on Amazon. Its in the same class as Vanadis 8 and 10V. The performance of these blades are equally admirable. Phone Hours (MST) 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. Heres a brief description of their impact on the resulting steels properties. The hardenable grade of titanium (Beta C Titanium) reaches up to 45 or so rc. 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. LC200N has similar properties to those two but with saltwater levels of corrosion resistance. Save my name, email, and website in this browser for the next time I comment. Three main characteristics differentiate steels from one another: corrosion resistance, hardness, and toughness. The following are less common steels, but theyre definitely worth tracking down. VG-10 steel also has the same level of toughness as 14C28N and the same level of corrosion resistance. H1 and 420 also have excellent corrosion resistance but are limited to lower hardness and edge retention. Non-stainless steels can be heat treated to 66 Rc or even higher depending on the particular steel. Cronidur 30 Spyderco is the only production company using this steel, though Michael Gavik of Gavko knives produced a number of customs in LC 200N. 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 The solid lockup and decent blade design make these two knives well suited for camping. blue steel Sorry about the misinformation. The best scenario is when the steel, heat treatment, and geometry are selected for the knife and the use. as you mentioned catra indicates the edge angle as being by far the most important variable. I love reading through all the data youve gathered and making note of all the trends (Im a physical organic chemist). We can predict edge retention of a steel within a relatively narrow band based on hardness and carbide volume. Chris Reeves version, which is about two points less hard than others, is quite good. These properties make steel a good choice for making kitchen, fishing, and everyday knives. (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.) There are a few aspects to your question, I think. Now that is power planer blades, but the principle stands, less carbon and alloy isnt the best for wood working and Id use a steel like 26C3 (1.25% C .30%Cr) for my hand tools and temper them to around 62 hard and use the best angle for wood shaving, not the best angle for cutting rope. Id like to quote some of your toughness, edge retention and corrosion resistance for balanced midfield steels, including yours, in some data tables. 14C28N Leek: D2 Leek: jonnymac44 Joined Sep 27, 2007 Messages 7,674 Oct 21, 2008 #2 Hey Michael, First off, the new 14C28N from Sandvik is just now hitting the streets, and I don't have any results just yet for you. 14c28n steel has a high Chromium and Carbon percentage. One such person is Dr. Larrin Thomas, a professional metallurgist raised by a knife maker and a giant knife nerd. However, D2 steel has better edge retention, while 14C28N offers a better sharpening experience. you can easily buy a $500 knive made out of 14c28n, which has nothing in it besides cr and a trace of ni. Many steel ratings seem to over-emphasize edge retention. It gets exceptionally sharp, a nod to its origins as a razorblade steel. Lots of information is still specific to this article, however. 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). 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). It is a Sandvik stainless steel that originally developed for razor blades. : 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. Stainless steels are another subset of high alloy tool steels that have enough chromium in them to have stainless levels of corrosion resistance. Im not hating on 80crv2 , Ive used it. For example, Bohler M390, CTS-204P, and CPM-20CV are all nearly identical and indistinguishable in practice. These are Chinese-produced steels that recently started showing up in Chinese-made knives. Vancron has a very fine microstructure so it would be tough to beat. Could you please compare it to Shirogami #1 and Agomi #1, I didnt find anything in terms of grain size ragarding thoese steels on the Internert. It would be really useful to have the raw data that backs the charts that you produce. However, Kershaw asked Sandvik to make their 13C26 steel more resistant to corrosion, and the result was 14C28N. Among Vancron SuperClean, Agomi #1 and Shirogami #1, Which one tends to have finer grain size and Sharper edge? Its not a regression line, it is just a line through the best steels. 2. 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. On the positive side, they are very easy to forge and grind. You showed some pictures in this article of the effect on what we might call "effective toughness" of thinner edge angles vs thicker edges in the same steel at the same hardness. Thats a little too far, but you get the point.). The 10V specimens tempered at 1000F were 4-5 ft-lbs while the specimens tempered at 4-500F were 7-8 ft-lbs. Hammering through hickory, digging at roots in sandy soil, and cutting around bone did nothing to chip, dent, or roll the edge of my 3V knives. 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. Steel high in carbides cant be stamped out; it must be cut by a waterjet or laser, which takes time and is more expensive. If you want to learn more than keep reading past the ratings. Vanadium carbides are among the hardest that form in steel, and chromium carbides are in between iron carbide and vanadium carbide. 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! As from features, for presenting d2 continue to grow in the knife industry, generally because of their working performance and reasonable price, a lot of superior low budget knives are building their reputation.
