It can withstand a lot of wear and tear. Because of its abrasion-eating hardness, knives with REX 121 come at an exceptionally high price. Still looking forward to magnacut making it into high volume production and use. That says to me theres a measurable abrasive quality to wood for sure. Another is that 8Cr13MoV is a generic name for a specific composition while AUS-8 is a name of a product by a specific company. The only thing putting me off immediately buying the p135 is the 14c28n steel. What would be the best deal to use I currently alternate between 20CV S35vn and D2. If youre having trouble finding the steel you want, see if another manufacturer makes something much like it. Mid-Range Steels 154CM D2 N690 VG-10 CTS BD1N 14C28N A2 1095 O1 H1 Budget Steels 440C CTS-BD1 440A 420 8Cr13MoV AUS-8 The Steels Should you continue to scroll further, you may find yourself lost in a seemingly endless list of knife steel wealth and knowledge. Softer steel usually forms larger burrs and they are more difficult to deburr. drop point There you said 7.6 for 420HC. It's more often pitted against the VG10 since both are widely popular high-carbon stainless steel grades. Yes its very easy to sharpen but it doesnt hold an edge at all. Instead, Vargo titanium uses a unique material called sintered titanium-ceramic alloy. The D2 steel compares nicely with 14c28n steel in terms of edge retention, as it's quite hard as well. And before you start arguing on behalf of the steel you think might be perfect, let me remind you that if your knife isnt perfect for a task, youll need to get another one that is! Austenitizing is the process where the steel is heated to high temperature prior to quenching (rapid cooling) to harden the steel. Become a patron and gain access to awesome rewards including early access to articles or a Knife Steel Nerds mug! Fine-carbide knife steels. Crucible intends SPY27 to be good all-around knife steel. CTS-204P and CPM-20CV are nearly identical steels made by other manufacturers. The best knife for you should meet your needs and fit your budget. Lots of information is still specific to this article, however. 3) catra is (as far as i know) the only accredited (iso/en) testing method. Manage Settings Steel with high wear resistance is more costly to manufacture, as the knife company goes through more abrasives to grind the knives. The steel loses some of the chromium in solution for corrosion resistance to form these fine carbides for hardness. 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. Here its 8. We all have our preference, but overall, preference leans towards the pocket knife with a clip. 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.). 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. Take a look at this edge retention test. FRN No mainstream companies use SM100, and the niche makers that do usually charge more than $1,000 for knives with SM100 blades. How long sharpen? 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? 2. The most traditional models of pocket knives have different parts, such as the handle and cutting performance. Theyll be fully attributed to you with website and Patreon links, obviously. Thats a pretty large difference in two budget steels that are often compared to each other. 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% . 8Cr13MoV still has some corrosion resistance, but not as much as D2. These steels are perfect for thin edges and high hardness. Jesse Jarosz, a custom maker from Montana, regularly uses AEB-L. The knife does dull faster. 52100 This grade can be treated cryogenically to improve edge retention. Is it similar but worse or better at one of the 3 things? 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. 420HC, 420, and 5160 all offer off-the-charts toughness. It mainly made for knife and it high in Chromium for excellent corrosion resistance. The steel is similar to Sandviks 13C26. When the blade gets messed up I just replace it. I did a test with knives in 440A (stainless), D2 (high alloy steel with some corrosion resistance), and 1095 (no corrosion resistance). I wrote an article about knife steel ratings available online in 2018, where I concluded that none of them were very good. Only a few years ago Elmax was pricey, but competition has driven it down to reasonable levels, making it a decent value. LC200N 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. 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. It would be really useful to have the raw data that backs the charts that you produce. Stainless steels are another subset of high alloy tool steels that have enough chromium in them to have stainless levels of corrosion resistance. Some steel companies charge more than others. I do not have rust issues with it (as long as I have a good finish) some heavy stonewashed finishes rust easier. worldwide, even the chinese have an equivalent (8cr13mov). 14C28N knife will dull faster, but it is easy to sharpen. However,M390, CTS-204P, and CPM-20CV are all pretty difficult to resharpen, so maintain that edge! This is the steel used in Swiss Army knives and is excellent for beginner sharpeners. And Michael Fitzgerald, Tim Marais, and Head VI for increasing their contributions. If you want to learn more than keep reading past the ratings. https://i0.wp.com/knifesteelnerds.com/wp-content/uploads/2021/10/stainless-toughness-10-19-21.jpg?w=757&ssl=1 Below shows pictures of a 61 Rc knife that was impacted with a 3/16 rod at different energy levels. I havent tested Sleipner yet. However, to choose the best knife for you must consider all the properties, including toughness, edge retention, corrosion resistance, and ease of sharpening. Hi Larrin Youve occasionally mentioned cryo treatment in your posts, including here with LC200N. A more obtuse edge angle is much more resistant to chipping than an acute edge. But a few overly vocal forgers were making claims about it that clearly were not true especially when comparing it to 5160. With steels that have a small amount of carbide the size of the carbides can be kept small through processing (see the AEB-L micrograph earlier in the article). They lack the carbon necessary to hold an edge, even during mild use. 14c28n is the most popular material for the knife: stainless steel and made by the Swedish company. S110V has improved corrosion resistance at the cost of some toughness compared to S90V. A new steel from Crucible, SPY27 launched in 2020 in the Spyderco Native 5and Para 3. Do honing steels as used on kitchen knives actually do anything useful? Any idea where it would be on the hardness and toughness scales? High toughness steels can be produced without powder metallurgy and also have low wear resistance for lower manufacturing costs. Though the volume of carbonitrides in the steel is relatively high. I have not provided a rating for ease in sharpening. The best steels with balanced properties include 4V/Vanadis4E, CPM-CruWear, and CPM-M4. thanks thats interesting. It had better than expected corrosion resistance due to the lack of chromium carbides, a behavior also seen in MagnaCut. Conventionally produced steels include AEB-L, A2, 52100, 12C27, 14C28N, and AUS-8/,8Cr13MoV. 2. Properties: 14C28N: D2: Edge retention: 4/10: 7/10: Ease of sharpening: 6/10: 3/10: Corrosion resistance: 4/10: 4/10: Toughness: ApexUltra is a steel that we are working on that had excellent properties in small batch production (50 lbs). Short of purposeful abuse, its all but impossible to chip an edge on an INFI blade. It has enough water-fighting properties that it can be used in marine environments. High wear resistance is not particularly necessary when only performing chopping, and its good ease in sharpening helps when having to restore the edges. 14C28N knives are easier to sharpen than D2 knives. Anyway, buff up the O1v and it cuts leather easily. D2 steel also resists chipping better than most stainless steel types. There one of the best reason that he is highly regarded as a knife designer. are after the ratings. 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. In addition, According to Sandvik, 14C28N steel is easy to work on, reducing production costs and hence affordable knives. There is a powder form, CPM-D2, and PSF27 is also very chemically similar. While higher hardness does lead to improved edge retention the bigger reason to have higher hardness is for resisting edge deformation. Spyderco announced Native 5 Salt with magnacut, but I saw test of magnacut with salt water and it grows corrosionso Salt with magnacut could be a flop. There is no such thing as a steel that is a 10 in both toughness and edge retention. Unfortunately a high amount of it decreases strength. 1095 stains easily and thus is often coated, especially in fixed blades. These steels offer a great balance of characteristics that work well, from big choppers to thin slicers. SG2 This means consumers should be able to maintain these quality knives at home. Like S90V, its a high-hardness steel, but its more balanced than S90V. All Rights Reserved. Marco, BSc Chem. VG 10 Steel, https://knifebasics.com/author/freelancer/, How To Choose Between The 14C28N And The D2, 14c28n Steel Is Good for Knife? 14C28N is a stainless steel that was developed specifically for use in knives. 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). I actually dont recommend that enthusiasts spend all that much time analyzing the exact composition of different steels and trying to guess their properties. Its high hardness and relatively high toughness also make it an excellent choice in cutlery. Actually, Id be thinking 14C28N, but I want to leave stainless out. I was recommended the Rat 1 in D2 and I also found that I really like the design of the Ruike p135 and p128. . i understand the samples were treated in the same way. But yes, I would assume that the general performance would still be relatively similar between them without evidence to the contrary. 14C28N and D2 knives are affordable high-end knives. 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. Knives are one of our oldest tools, so it makes sense that they have evolved into thousands of styles since the first person chipped one out of stone. Steels that are higher in hardness and wear resistance are usually lower in toughness. D2. Combination of knife steel properties. A European powder-metal steel used in higher-end knives, Elmax has an advanced formula, and the result is a very good all-around steel, a generation ahead of formulations like 154CM. Rowens heat treat on ESEE knives that use 1095 is exceptional; KA-BARs is less so. Phone Hours (MST) My test is for comparing different steels, not necessarily for a go/no go test for saltwater applications. Its a very hard steel and is exceptionally difficult to sharpen. The Kershaw Leek is a most popular EDC knife that design by legendary custom knife maker Ken Onion. Pretty interesting that regrinding a knife you already have can seemingly take its performance to that of significantly better steels. rex 121 Maxamet is one of two current high-hardness kings, with HRc marks in the high 60s approaching 70, a hardness usually only seen in carbide steels. 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. Anyway, astute comment, but edge retention does mean a lot in woodworking. On the other hand, edge stability in terms of micro chipping and edge folding is also good. The vivid patterns visible in Damascus steel come from the acid etching process in a ferric chloride solution. . 14C28N steel is the improved version of 13C26 with better rust resistance. The 10V specimens tempered at 1000F were 4-5 ft-lbs while the specimens tempered at 4-500F were 7-8 ft-lbs. . Low Alloy tool steels have small alloy additions to increase hardenability so they harden more easily in oil rather than water. Get for a complete guide about other steel; you can read 14c28n vs 8cr13mov reviews. Cronidur 30 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 improves wear resistance and hardenability. Three main characteristics differentiate steels from one another: corrosion resistance, hardness, and toughness. Most steels use carbon to increase hardness, but 14C28N uses nitrogen, boosting hardness without the normal penalty of increased corrosion. Almost all of the knives in my EDC rotation are Spydercos, in exotic steels. To reiterate the clearer part, I wonder if toughness increases faster than edge retention decreases as an edge gets thicker. while its a very intuitive method and a simple way to e.g. They differ little in composition and treatment. However, it can be somewhat complicated because an edge can dull from many causes wear, micro-chipping, deformation, or corrosion. What makes 1.4116 such a bad performer in regards to toughness on par with ultra high carbide steel like S125V? 14C28N VS Steel. This is a midprice steel with matching performance. [Steel Knife Review], Best survival knife sword: 5160 steel Review, What is VG 10 pocket knife? 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). ZDP-189 can tarnish, though not as easily as 3V. Elmax If the steel is overheated in austenitizing, very large reductions in toughness are possible. We did the research to help you find the best hunting knife for your needs and budget. So presumably, wear resistance would be in the 3.5-4 range and toughness in the 5.5-6 range. Choose a factor below to start sorting. Because of its difficulty in sharpening and machining, its very rarely used and comes with a high price premium. Thanks! In general, higher carbon steels have higher edge retention but lower toughness. I personally don`t care about stainless (sic! 14c28n steel has a high Chromium and Carbon percentage. the following is not a critique, just a few thoughts to maybe put the relationships into a wider perspective and point to additional dimensions. 14C28N VS D2 Attributes: 14c28n: D2 . 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(%). 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. 14C28N steel is as a result of a more corrosion resistant version of the 13C26 steel. Should you continue to scroll further, you may find yourself lost in a seemingly endless list of knife steel wealth and knowledge. 14C28N steel is known to offer the highest toughness levels out there. Not as tough as the best carbon steels, it's tougher than most . But which? For example, increasing edge retention from Z-Tuff to 3V (100 mm in the CATRA test) led to a drop in over 10 ft-lbs, a similar drop is seen by going from 3V to CPM-CruWear. the problem is in the innumerable combinations of grades, grains sizes and coatings available. I have an article that lists off the major mistakes often made in heat treating. The value being slightly different doesnt mean its an outlier or measurement error. The stainless steel rating. D2 is a tool steel used in industrial settings. 14C28N knives offer better toughness than D2 knives. CPM 3V When describing the characteristics of a steel, a few common attributes are commonly talked about. 14C28N Vs D2 . For high wear resistance and edge retention you want a large amount of hard carbides. Rather than upgrade from D2 to M4 or S30V just drop the angle from 40 degrees to 30 degrees. And Ive done a lot of experimental work on knife steels where I feel more confident in my own ratings. It boasts an incredible ability to continue cutting long after it seems dull. And its not made of steel. What carbon/tool steel would you choose for a survival knife if a PM steel was too expensive? Hello LARRIN, do you have a Rough estimate on when ApexUltra (as well as more Magnacut) will become available? its like with cars, most of them are not a corvette or a porsche. Have you tested K390 sufficiently to be able to rate it? The unique process used to make LC 200N results in a fine-grain structure. One is certainly anti-China bias, as you pointed out. Its not a regression line, it is just a line through the best steels. Many steels are very similar to one another but go by different names from different manufacturers. On the other hand small but mighty, the pocket knife provides both in professional performance and in arresting good looks. Among Vancron SuperClean, Agomi #1 and Shirogami #1, Which one tends to have finer grain size and Sharper edge? 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. I have a few examples below for steels that I have ranges of hardness tested for both toughness and edge retention. I guess that was before I started reading. There is one exception: Bucks 420HC (Buck and onlyBuck) is produced using a proprietary heat treatment. This does not predict which knife will cut longer or be more resistant to chipping. MC66 D2 is another medium-range tool steel. In many cases, the D2 edge sharpness may last a bit longer. The ESEE had significant edge damage while the MagnaCut knife did not. Steels with only vanadium carbides have the best balance of properties because the hardness of carbide matters for edge retention but doesnt for toughness. In fact Id be delighted to have your experience checking my thinking! The solid lockup and decent blade design make these two knives well suited for camping. 1.4116 got a 2.5 for toughness and edge retention where as 420HC got a 9 for toughness and a 2.5 for edge retention. They represent the absolute best performers on the market in terms of their specific attributes. BD1 isnt terribly hard but sharpens easily. https://knifesteelnerds.com/2018/12/10/cryogenic-processing-of-steel-part-2/ D2 at 58 hard will cut much more rope than AEB-L at 62. 7:00am-5:00pm, 10am-7pm Tuesday - Friday So, its hard steel is easy to sharpen. Therefore, you cannot purchase the knife for use in corrosive environments. 8am-5pm Saturday. The material increase machinability and strength. They have many similarities, including their high hardness, strength, and wear resistance. Thanks for the Article Larrin, It is most useful for steels with large amounts of carbide but also helps to be able to add certain carbide types. 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. In other words, heat treating a steel to its maximum hardness does not necessarily mean reduced corrosion resistance. Lets talk about the clip-on pocket knife. Im a woodworker and Im interested in making better performing plane irons and chisels. Many steel ratings seem to over-emphasize edge retention. These are Chinese-produced steels that recently started showing up in Chinese-made knives. Also Mo additions improve corrosion resistance for a given amount of chromium. They were two different tests (different batch of steel, different person heat treating, etc). 8cr13mov if proper slicing geometry its good budget steel if you dont rust it and no prying or screwing its ok cutting steel. However, D2 steel has better edge retention, while 14C28N offers a better sharpening experience. This is a powder-metal steel also produced by Crucible. 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. Thats a little too far, but you get the point.). However, even in this case there is the complicating factor of carbide and abrasive hardness. However, it falls behind the Bohler steel in corrosion resistance. Approximately the same hardness, yes. Its probably in between Vanadis 8 and 10V. Plus the charts get messier, and I dont always have data for a wide range of hardness values. This is about comparing steels to each other rather than a limitation of an individual steel. in relation to hardness). Did you change the estimate based on more testing? However, this edge retention comes at the cost of sharpening ease for D2. (Some crazy folks clean their Swiss Army knivesin adishwasher. Heat treatment refers to the heating and cooling steps employed to achieve your knifes proper balance of attributes. Hit like and all t. D2 is mainly considered decent budget steel that comes with better edge retention than the 14C28N. Only a skilled blacksmith can make Damascus steels, so they tend to be expensive. The 1.4116 I tested has large carbides in it which is presumably the reason for low measured toughness: https://knifesteelnerds.com/2019/05/26/new-micrographs-of-42-knife-steels/. All of the experiments shown below are possible thanks to supporters. Carbon steels are those that have primarily carbon added to them with some Mn or Si as well. 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. Sandvik 14C28N steel offers excellent corrosion resistance, exceptional toughness, good edge retention, and is easier to sharpen. In other words, Rex 121 would be the most difficult to sharpen and 5160 and 8670 would be the easiest. Thank you for the accurate data. Can you contact me via my email address so I can send you a copy in PDF and epub. Its very similar chemically to RWL 34 and ATS-34. They made planer blades out D2 for its edge retention. In general, steels look worse as you go up in hardness because the toughness is reduced by more than the edge retention is increased. D2 holds it for longer. But to learn more about these and other attributes, read our related outdoor knife buyers guide. Is this at the same hardness? 1095 But unlike most high-end steels, SPY27 is an easily user-serviceable powder steel. AEB-L is rarely found on production knives but can be found on custom knives easily. 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. CPM-S90V, CPM-S110V, CPM-10V, and Bohler K390 each fit in this category. Furthermore, because of its ultrahigh hardness, Maxamet is very prone to corrosion, probably worse than 1095. Chris Reeves version, which is about two points less hard than others, is quite good. HAP40 It's like the difference between average 420HC and Buck's 420HC with the Bos heat treatment, only from a better starting point. An example of data being processed may be a unique identifier stored in a cookie. Below are some great ways to make your knife your own. Reddit and its partners use cookies and similar technologies to provide you with a better experience. Steels without these attributes are much less costly. Not impractical fantasy knives, but these two knives that have a col look to them. Maxamets hardness results in incredible edge retention and a nightmarish sharpening and machining experience. In the context of a knife this would be chipped edges or broken knives. and corrosion resistance than the 420HC steel. and get better and longer-lasting performance? These two knives are a little bit more than a pretty face. Dr. Thomas is a friend of ours here at Blade HQ, and with his help, weve worked to create this knife steel guide. EDGE RETENTION . Its so high in hardness that Maxamet knives usually ship with desiccating packages. AEB-L Toughness is the resistance to chipping or breaking.
