Blue Super and 1.2562 have higher edge retention but relatively low toughness. Generally this is code for difficulty in abrading away steel. Below shows a comparison of carbide structure between D2 and CPM-D2, and then toughness measurements between the conventional and PM versions of CruWear, D2, and 154CM. Hi Larrin, thanks so much for writing this blog and putting so much reliable information into such an accessible form. It has enough water-fighting properties that it can be used in marine environments. If you need something that soaks up abuse, try 3V. The D2 steel compares nicely with 14c28n steel in terms of edge retention, as it's quite hard as well. Vanadium carbides are among the hardest that form in steel, and chromium carbides are in between iron carbide and vanadium carbide. 14C28N VS S30V S30V steel provides improved corrosion resistance, sharpening ease, and edge retention. This is a non-powder steel produced by American steel company Carpenter. AEB-L and 14C28N are the best in the high toughness group. Each test is done with 3 or more specimens to get a good average. 14C28N vs. D2. Some of our partners may process your data as a part of their legitimate business interest without asking for consent. This is a virtually stain-proof steel suitable for all sorts of aquatic environments. But its very cheap, and, when ground appropriately, it can be a real winner from a value standpoint. The sharpening makes the knives easy to maintain because they dull faster and require frequent sharpening. AEB-L and 14C28N are the best in the high toughness group. Some steels are more difficult to manufacture for the steel company or have more expensive alloying elements so the cost is increased. Short of purposeful abuse, its all but impossible to chip an edge on an INFI blade. Manage Settings However, it is not really known how many different companies are making 8Cr13MoV (or at least I dont know), it could be that it is one manufacturer that is dominating the market. 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. D2 knives, on the other hand, are challenging to sharpen. These two knives are a little bit more than a pretty face. How long sharpen? However, Kershaw asked Sandvik to make their 13C26 steel more resistant to corrosion, and the result was 14C28N. im led to believe tha the melting procedure is more important with these steels than the exact composition. HA! Knifemakers use dozens of steel types to create knife blades. 14c28n Steel Is Good for Knife? Here's The Best Review For - Milkwood 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. Or even a 7 in both categories. Sandvik 14c28n Steel Review - KnifeUp Are you okay with that? 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. I have an article that lists off the major mistakes often made in heat treating. It can dull your edge, cause pitting, and damage the structural integrity of your knife. Heres a brief description of their impact on the resulting steels properties. I tested its edge wear resistance but not its toughness yet. Austenitizing is the process where the steel is heated to high temperature prior to quenching (rapid cooling) to harden the steel. European steel company Sandvik produces 14C28N, a non-powder metallurgy steel. Used in knives since at least World War II, 1095 performance varies considerably with an abundance of tweaks in the recipe and heat treat. D2 steel, on the other hand, is tool steel, and its knives shine on edge retention and wear resistance. 14C28N is a stainless steel that was developed specifically for use in knives. Knife Steels Rated by a Metallurgist - Toughness, Edge Retention, and Not every element is shown in the charts. Tanto But yes, I would assume that the general performance would still be relatively similar between them without evidence to the contrary. It was originally developed for use as ball-bearing steel by NASA. 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. 440A has more chromium in solution along with a small addition of Mo, but has significant amounts of carbide so the two are an interesting comparison. But in my experience, it has been nothing but great. So, its hard steel is easy to sharpen. 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. Cookie Notice CPM 10V We did the research to help you find the best hunting knife for your needs and budget. The greatest living knifemaker and one of the greatest knifemakers of all time, Michael Walker, calls AEB-L one of his favorite steels. I was guessing 5.5 based on your rating of CPM-154. Marco, BSc Chem. 2. The main downside is the steel is more difficult to heat treat and can't go harder than about 60 or perhaps 61 Rc. There was significant sharpness loss with 1095, almost none with 440A, and D2 was in between. SG2 Thats a pretty large difference in two budget steels that are often compared to each other. But among the steels youll find at Cabelas and the like, this is a pretty good choice. You will get an ultra-sharp edge with 14C28N knives. 12C27 steel is extremely popular in the US knife market for its high hardness, high wear resistance, and great corrosion resistance. 14C28N steel is the improved version of 13C26 with better rust resistance. Socould you please clarify which steel is the outlier and which is the line>. LC200N has similar properties to those two but with saltwater levels of corrosion resistance. Its an update of its 12C27 and 13C26 steels, which were developed for use in shaving razors. Some of these steels also have vanadium (CruForgeV) or tungsten (Blue Super, V-Toku2, 1.2519) for increased wear resistance. 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. Another very tough and highly wear-resistant steel grade is the D2. Steels that can be high in edge retention and toughness are desirable for general use knives. LC200N has similar properties to those two but with saltwater levels of corrosion resistance. What carbon/tool steel would you choose for a survival knife if a PM steel was too expensive? However, there are other factors. Does that mean that companies like Tops, Kabar and ESEE would be better off using 420HC instead of 1095 on their fixed blades? It mainly made for knife and it high in Chromium for excellent corrosion resistance. There is no single category that means that a steel is more premium or better than another. I see tables that compare Toughness,Edge Retention,Corrosion Resistance. If youre having trouble finding the steel you want, see if another manufacturer makes something much like it. Only a skilled blacksmith can make Damascus steels, so they tend to be expensive. 14C28N vs D2: Overview 14C28N steel is a high-end stainless steel created by the Swedish company Sandvik. Check out theGiantMouse Vox/Anso ACE Iona Liner Lock Knife at $99, for example. It improves wear resistance and hardenability. Wusthof Classic Ikon 8-Inch Cooks Knife Review, Victorinox Fibrox Straight Edge Chefs Knife Review, What is Cts bd1 steel? Its high hardness and relatively high toughness also make it an excellent choice in cutlery. Knife Steel - BladeReviews.com All about 14C28N Steel - HDMD Knives Blog Thats a little too far, but you get the point.). However, the 14c28n provides perfect edge retention with a maximum hardness of 62Hrc and the mixture of Chromium and Carbon. 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. I think they are complementary and you should watch/read both. But SM100 is not widely available, hard to heat treat and grind, and exceptionally expensive. Sandvik later came out with 14C28N which is a slightly improved version of 13C26. does 1.4116 deserve the title of title of ultimate trash steel? 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. Despite its wonderful performance, XHP is actually not terribly expensive compared to other high-end, all-around performers. Different companies can vary some between each other making the same product, while a single company is going to be more consistent. REX 121 is a powder steel produced by Crucible. But its lightyears ahead of the alternatives, specifically titanium-bladed knives. H1 and 420 also have excellent corrosion resistance but are limited to lower hardness and edge retention. The steel falls under the Sandvik series of steels and makes one of the 7 steel grades in this family including 12C27M, 14C28N, 13C26, and others. 14c28n vs D2 Steel. Extra kudos for your mathmatical steel composition to edge holding model thats really impressive work. Phone Hours (MST) 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). while its a very intuitive method and a simple way to e.g. This particular steel grade allows for the highest attainable hardness without. 1.4116 A lot of custom makers also like S110V, including the great RJ Martin. Like S90V, its a high-hardness steel, but its more balanced than S90V. Bohler N690Co Stainless Steel: Is N690 a Good Knife Steel? - KnifeGuides Steels that are improperly heat treated have excess retained austenite which makes them extremely difficult to deburr. An example of data being processed may be a unique identifier stored in a cookie. What is pulling that line high and to the right? Which knife for best? 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. D2 steel is a ordinary tool steel and knife steel. This is a powder steel produced by American steel company Carpenter. You cannot leave your 14C28N knives in water overnight and expect them not to rust. Several factors arent related to the steel you choose but seriously affect the nature of your knifes performance. Sandvik 12c27 Stainless Steel Review: Is it Really Great 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. Damascus or pattern welded steel is a result of combining two steels together. Its tough, but thats about it. That is an air-hardening- high carbon, high chromium tool steel. We use a subsize, unnotched chapy test with 2.5 x 10 x 55 mm dimensions. 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. If you purchase this types of knife, without any hassle you can easily re-sharpening. 14C28N knives will handle challenging and demanding applications without chipping, cracking, or breaking. MagnaCut has the lowest chromium of any of the below steels but all of its chromium is in solution (no chromium carbide) and the fact that it has no chromium carbide also gives it the maximum level of corrosion resistance for a given amount of chromium. We all have our preference, but overall, preference leans towards the pocket knife with a clip. But which? Both steel types don't chip easily, but 14c28n steel is easier to sharpen. I have a bachelor's degree in Mechanical engineering with a specialization in material science. Though technically not a stainless steel due to its composition, in use it performs exactly like one. 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). I know that one does not normally make knife blades of titanium, but I gather that Ti is extremely corrosion resistant, used for saltwater applications, etc. 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. Often used for combat knives. at least it has some vanadium over the 420hc. I feel like it sharpens as easy as D2. The best knife for you should meet your needs and fit your budget. If the properties of a knife meet your knife needs and it has the above characteristics, then it qualifies as a quality knife. However, D2 steel has better edge retention, while 14C28N offers a better sharpening experience. Most of the discussion of how the ratings were generated, various caveats and details, etc. YMMV 14c28n vs d2 - Which Model For Best - Knifeyellowpages 14C28N vs D2 - knifebasics.com imo o lot depends on how the blade is sharpened. In general, higher carbon and higher vanadium steels have higher wear resistance and edge retention but lower toughness. Though technically not a stainless steel at least 14% chromium, and D2 usually has 12% its relatively corrosion-resistant. When the blade gets messed up I just replace it. Around 61 Rc usually. These steels offer a great balance of characteristics that work well, from big choppers to thin slicers. Below I have shown the difference in carbide volume between AEB-L, CPM-10V, and Rex 121 to get an idea of how much more carbide there is in the high edge retention steels. Knife Steel Guide - Knife Life - Blade HQ The best steels with balanced properties include 4V/Vanadis4E, CPM-CruWear, and CPM-M4. Elmax Sandvik 14C28N steel offers excellent corrosion resistance, exceptional toughness, good edge retention, and is easier to sharpen. Theres also a line of green triangles a bit below that. VG 10 Steel, https://knifebasics.com/author/freelancer/, How To Choose Between The 14C28N And The D2, 14c28n Steel Is Good for Knife? While not a powder steel, 154CM is widely used in nicer knives. There is no such thing as a steel that is a 10 in both toughness and edge retention. This steel, as the name implies has a professional styling to it. We can predict edge retention of a steel within a relatively narrow band based on hardness and carbide volume. The big difference in properties vs the low alloy steels, however, are the harder carbides that are found in these steels. 14C28N is essentially AEB-L (or perhaps more accurately Sandvik 13C26), but with improved corrosion resistance. If the steel is overheated in austenitizing, very large reductions in toughness are possible. High wear resistance is not particularly necessary when only performing chopping, and its good ease in sharpening helps when having to restore the edges. In general, the more carbide the steel has and the larger the carbides the lower is the toughness. 14C28N knives offer better toughness than D2 knives. These images are taken from my book Knife Engineering. It is among the best steel that will offer exceptional toughness while still maintaining excellent corrosion resistance. Also, what kind of steel is used for utility knives? Hes already done a three part series on cryogenic treatment: 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. Top quality steel yields perfect toughness, edge retention, wear and corrosion resistance, an easy to sharpen, long lasting and durable everyday carry that will fast become a user favorite. 14C28N You need a hard medium to sharpen it like diamond or boride. 0.62% of Carbon: Makes knives harder and more resistant. Thanks! . The D2 version is heavier and harder, but doesn't cut as smoothly. These steels are best for knives that dont see impacts and are some of the most difficult to sharpen. The both blade are equally wear resistant. Theres a green triangle at about RC 60.5 and toughness over 40. Contact me if you have any questions or input! When it debuted, Sal Glesser described XHP as a combination of D2s hardness and 440Cs corrosion resistance. then you have zirconia and diamond coated blades. Notice that with the same edges on the same media, the 9Cr18Mov from Real Steel performs about as well as the average Chinese D2. However, to choose the best knife for you must consider all the properties, including toughness, edge retention, corrosion resistance, and ease of sharpening. I like it in the Seki City Spydercos, but I would like to know what ratings you would give it. This is good for ease in heat treating in large batches and for even cooling that greatly reduces warping and size changes. This means consumers should be able to maintain these quality knives at home. Steels with only vanadium carbides have the best balance of properties because the hardness of carbide matters for edge retention but doesnt for toughness. If youre looking for all all-around best knife steel, youd be hard-pressed to find one better than Bohler Uddeholm M390. But Ive found it lacking in hardness, even when compared to cheaper steels like AUS-8. And steels with at least 10% chromium are probably stainless, except for several important exceptions like D2 and ZDP-189. Nitro V vs 14C28N Last but not least, 14C28N contains comparatively more vanadium elements which makes the carbides more harder and strong, which gives 14C28N a better edge retention. Hi there, LC 200N is an elite performer, with high hardness, high toughness, and off-the-charts corrosion resistance. The consent submitted will only be used for data processing originating from this website. Now that we know what each factor represents, we can see how the steels rank against one another. In particular, I really care about the toughness / hardness part. VG-10 steel also has the same level of toughness as 14C28N and the same level of corrosion resistance. D2 seems to run at high hrc. Toughness is a measure of how much resistance a steel has to fracturing. 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. My name is Jonathan M, and Im a passionate Mechanical Engineer, a knife enthusiast, and the author of this website. Continue with Recommended Cookies. Corrosion is not only cosmetic. The reason is because sharpening and edge geometry will also greatly control properties. Any thoughts how Sleipner might fare in the ratings? Yes its very easy to sharpen but it doesnt hold an edge at all. If you would like to change your settings or withdraw consent at any time, the link to do so is in our privacy policy accessible from our home page.. The steel comes with increased wear and abrasion resistance properties. 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. PESR would be an interesting topic too (also tied to LC200N). 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. This is a nitrogen steel that is extremely corrosion-resistant so much so that its used in knives designed to go in salt water, among the most difficult conditions knives are used in. Thank you for putting this together, incredibly useful! The steel is susceptible to overheating during hardening do not overheat. ZDP-189 can tarnish, though not as easily as 3V. But weve tested this metal in the form of the Sobata 398 for nearly a year and have been continually impressed. Both of those things are no longer an issue as I now have way too many articles and a book. 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. Many steel ratings seem to over-emphasize edge retention. there seems to be an optimal procedure for every alloy (provided its heat treated to industial standards). Become a patron and gain access to awesome rewards including early access to articles or a Knife Steel Nerds mug! Stainless steels usually top out around 64 Rc and may require careful heat treating to get there. It isnt impossible, but contrast may not be very good and the austenitizing temperatures of the two steels arent very compatible. High alloy tool steels are designed to be air hardening, so they can be cooled even slower than the oil hardening steels found above. Is 440A really that much better than 420HC, or have you found a narrower gap? Therefore powder metallurgy is not necessary for certain steels, or could even be slightly detrimental. 420 Simple, non-stainless steels of medium carbon content like 5160 also boast high toughness. Alpha Knife Supply sells 26C3 btw. It can withstand a lot of wear and tear. There is a powder form, CPM-D2, and PSF27 is also very chemically similar. The 25 dps sharpened knife saw almost no edge damage with 2 ft-lbs while a 15 dps edge saw a significant chip with only 0.3 ft-lbs and catastrophic chipping with 1.4 ft-lbs. Its actually quite good, low-cost steel that performs like midprice steel. I've heard d2 is miles better and i dont want to pay 90 for the p135 and get a significantly inferior blade to paying 110 for the D2 Rat. Its a good balance between all three attributes, being relatively hard, tough, and corrosion-resistant. 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). Micarta For more information, please see our as you mentioned catra indicates the edge angle as being by far the most important variable. This is to keep the focus on the elements that are making the biggest difference. Privacy Policy. Lots of information is still specific to this article, however. . Its not bad, but you can find better in the market at the same price. its like with cars, most of them are not a corvette or a porsche. D2 is mainly considered decent budget steel that comes with better edge retention than the 14C28N. However, even in this case there is the complicating factor of carbide and abrasive hardness. The very good toughness of MagnaCut meant that it didnt chip despite this relatively high hardness and the difficulty of the test. Are you looking for 14c28n steel with other steel? In general, higher carbon steels have higher edge retention but lower toughness. Spyderco is the only production company using this steel, though Michael Gavik of Gavko knives produced a number of customs in LC 200N. AR-RPM9 Cold Steel still uses VG-1 on some knives, and, for the money, it does well. 8Cr13MoV still has some corrosion resistance, but not as much as D2. third and most important is what happened to the burr. The Sandvik 14C28N has a very thin and sharp blade that is perfect for slicing through things.
