Steels 7Cr and below arent worth your time or money. SG2 One important concept I want to hammer home is that there isnt one property that is most important. However, even steel with the best corrosion resistance can rust without proper care. 14C28N VS D2 Attributes: 14c28n: D2 . s30v drop point 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% . Vancron would work well in a kitchen knife. Knife Steel - BladeReviews.com They represent the absolute best performers on the market in terms of their specific attributes. In all of the cases above, properties are greatly controlled by carbides. CROMOVA This doesnt necessarily mean they have terrible toughness, but they have limitations. If you need something that soaks up abuse, try 3V. 14C28N is essentially AEB-L (or perhaps more accurately Sandvik 13C26), but with improved corrosion resistance. It is most useful for steels with large amounts of carbide but also helps to be able to add certain carbide types. Thanks! Save my name, email, and website in this browser for the next time I comment. Type 8Cr, the more common formulation, is worse than AUS-8: a little more prone to corrosion and not quite as hard. Can you contact me via my email address so I can send you a copy in PDF and epub. It shows 3 stainless steels from 750-800tcc but the edge retention graph only has 1 SS in that range, S90v. Did you change the estimate based on more testing? in relation to hardness). Phone Hours (MST) I especially appreciate the geometry/edge retention/toughness comparison with photos. Is 440A really that much better than 420HC, or have you found a narrower gap? Its not a regression line, it is just a line through the best steels. So, its hard steel is easy to sharpen. I have the average composition of the steels rated above (plus some extras) so you can see what the different names refer to. . 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! 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. This is a midprice steel with matching performance. ZDP-189 can tarnish, though not as easily as 3V. in the correct place for the stainless-toughness-edge-retention graphic? Even premium steels can have poor performance with poor heat treatment. S45VN Approximately the same hardness, yes. 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. You can read an article I wrote on budget steels here. Start comparing steels. What it is: 14C28N is a Sandvik stainless steel commonly used in razors and kitchen knives. document.getElementById( "ak_js" ).setAttribute( "value", ( new Date() ).getTime() ); Enter your email address to subscribe to this blog and receive notifications of new posts by email. But I think it would have much higher toughness than any of the steels on the chart. 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. Read more. A new steel from Crucible, SPY27 launched in 2020 in the Spyderco Native 5and Para 3. Guide to the Best Knife Steel | Knife Informer 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. 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. AEB-L Find your right answers here! As wear resistance is increased the differences between conventional and powder metallurgy steels become greater. Steels patina in the acid at varying rates which allows for one steel to etch darker than the other and show that famous patterned contrast. That provides 14% Chromium and offers excellent corrosion resistance. 14C28N is a type of high-performance stainless steel used in knife-making. 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. 420HC doesnt hold an edge well, but its relatively stain-resistant and tough. The ratings in this article rate ease of sharpening primarily based on wear resistance, but if a knife is difficult to sharpen, there may be other factors in play. High wear resistance steels are more expensive to buy and to process, especially since many require powder metallurgy. Many custom makers enjoy AEB-L, as its easy to machine but still has a high hardness, around 62 HRc. G10 Stainless steels usually top out around 64 Rc and may require careful heat treating to get there. 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. Low Carbon steels like AEB-L wont hold up to wood cutting even though it can hit 64 hard, it just doesnt have enough Carbon. Each test is done with 3 or more specimens to get a good average. you can easily buy a $500 knive made out of 14c28n, which has nothing in it besides cr and a trace of ni. 14C28N vs D2: Overview 14C28N steel is a high-end stainless steel created by the Swedish company Sandvik. 1) the cvn number is just that, a number. Here its 8. In reality hardly difference. 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. Like S90V, its a high-hardness steel, but its more balanced than S90V. Though the volume of carbonitrides in the steel is relatively high. These steels offer a great balance of characteristics that work well, from big choppers to thin slicers. Obviously Ill let you check the manuscript prior to publication. Sorry, most of my previous comment was borderline word salad. Hit like and all t. A more obtuse edge angle is much more resistant to chipping than an acute edge. But in use, Ive found nothing that withstands the abuse that 3V can take. Is it similar but worse or better at one of the 3 things? Im going to give the ratings first and then give more explanation about how the ratings were created. Non-stainless steels can be heat treated to 66 Rc or even higher depending on the particular steel. Like 154CM, its a good compromise between all three steel attributes. That comes with an excellent return of experience that makes it ideal for the manufacturer of outdoor and tactical knife blades. LC200N has similar properties to those two but with saltwater levels of corrosion resistance. Its very hard, tough, and corrosion-resistant. It's like the difference between average 420HC and Buck's 420HC with the Bos heat treatment, only from a better starting point. [Steel Knife Review], What is 14c28n steel? Been here before? Vanadium carbides are very large with conventional production of steels but are very small with powder metallurgy. In use, its very similar to 440C and VG-10. VG 10 Steel, https://knifebasics.com/author/freelancer/, How To Choose Between The 14C28N And The D2, 14c28n Steel Is Good for Knife? Its soft, with very low carbon content. You need a hard medium to sharpen it like diamond or boride. Alpha Knife Supply sells 26C3 btw. Give it a couple of weeks, and feedback will start pouring in. But in my experience, it has been nothing but great. first there might have been some annealing going on (even if its was a microscopic level) and the steels might have reacted differently. 14C28N is offered on midprice knives and is one of the better steels on a dollar-for-dollar basis. H2 The 10V specimens tempered at 1000F were 4-5 ft-lbs while the specimens tempered at 4-500F were 7-8 ft-lbs. I test corrosion resistance of steels by heat treating 1 x 1.5 inch coupons, finishing to about 400 grit, and then spraying with water. Very acute edges are more brittle but remain sharp for longer and cut very well. Its so high in hardness that Maxamet knives usually ship with desiccating packages. Heres The Best Review For You (2021), D2 knife blade offers high edge retention, Dulls faster, Requires frequent sharpening. Furthermore, because of its ultrahigh hardness, Maxamet is very prone to corrosion, probably worse than 1095. 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. In some previous articles I have shown the balance between my toughness and edge retention measurements such as in the following chart, where the high alloy non-stainless are in orange and the blue are stainless: However, one issue with these charts are that difference in toughness is that a linear scale for toughness is a bit misleading for visualizing practical toughness differences. Is that regression line (or other trend line?) Stainless steels are another subset of high alloy tool steels that have enough chromium in them to have stainless levels of corrosion resistance. Some steels are cooked up specifically with this in mind and are very difficult to make rust. This steel, as the name implies has a professional styling to it. What is AUS10A Steel? - knife Insight 2) you do not go into the sharpening in much detail. This is a major tradeoff between improved cutting ability and edge retention with an acute angle vs a strong and chip resistant edge with an obtuse angle. Corrosion on knife steels most usually takes the form of rust, patina, and staining. I do not have rust issues with it (as long as I have a good finish) some heavy stonewashed finishes rust easier. Choose a factor below to start sorting. The steel is similar to Sandviks 13C26. That way you can get into the steel ratings quickly. Extra kudos for your mathmatical steel composition to edge holding model thats really impressive work. A lot of custom makers also like S110V, including the great RJ Martin. D2 steel also offers similar toughness levels as the 14c28n steel, so both aren't really prone to chipping with proper use. Lets talk about the clip-on pocket knife. The unique process used to make LC 200N results in a fine-grain structure. The high hardness makes it all but impossible to sharpen and machine. Its easy to sharpen. S90V D2 is another medium-range tool steel. 14C28N knives will handle challenging and demanding applications without chipping, cracking, or breaking. 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/. The Vargo Sobata 398 is unlike any other knife on this list. Its in the same class as Vanadis 8 and 10V. This makes it a great choice if you don't have . They were two different tests (different batch of steel, different person heat treating, etc). 14C28N knives offer better toughness than D2 knives. 1095. This is a powder-metal steel also produced by Crucible. and why would anyone want to use it when 420HC looks so much better for a simple stainless steel option. The difference in properties between 14C28N and D2 steel is very clear. However, many kinds of wood are REALLY tough and very hard on blades. So setting edge geometry for the type of knife and intended use is very important. We use a subsize, unnotched chapy test with 2.5 x 10 x 55 mm dimensions. 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. High Alloy Tool Steels and High Speed Steels. To view the purposes they believe they have legitimate interest for, or to object to this data processing use the vendor list link below. Is there some way we might predict the relative "effective toughness" of different steels at different hardness and at different edge angles? Your email address will not be published. It mainly made for knife and it high in Chromium for excellent corrosion resistance. Aluminum oxide is used in most common sharpening stones and it is softer than vanadium carbide, which makes sharpening high vanadium steels more difficult. Notice that with the same edges on the same media, the 9Cr18Mov from Real Steel performs about as well as the average Chinese D2. False treatment and geometry upheld by Made in USA is like buying 8Cr from China (except late A.G) My personal experience tops with Vanadis 4E, CPM-M4, RWL-34 and the likes. Finally, in this 14c28n vs d2, we hope you get the right one. The ESEE had significant edge damage while the MagnaCut knife did not. Its very corrosion-resistant and quite tough. I like it. This is an American-made powder steel. There is no such thing as a steel that is a 10 in both toughness and edge retention. I have a Winkler Knives Recon model in 5160 steel and even though the knife model is ok, the steel is shit. Thanks to its very high hardness (64-66 HRc compared to the average of 58-62 HRc), ZDP-189 can be ground thinner and sharpened less often. Deburring of edges often takes even longer than removing material to produce the edge. Powder metallurgy is a technology designed to maintain a small carbide size. The Complete Guide to Knife and Tool Steels - Heinnie Haynes AEB-L and 14C28N are the best in the high toughness group. So youre right that a D2 blade will cut more CATRA cards than an AEB-L blade *when theyre both sharpened to the same angle* but AEB-L has much better toughness and can therefore handle being sharpened to a more acute angle without chipping, and a more acute angle is more important to continuing cutting ability than wear resistance is. Would love to see where S7 sits on the Corrosion/Edge/Toughness meter. 8Cr13MoV is comparable to the Japanese AUS-8 but containing slightly higher carbon content. at least it has some vanadium over the 420hc. Therefore, ensure to wash and dry your knives after use to keep the rust away. 14C28N VS Steel. My favorites of the high edge retention group are Vanadis 8 and CPM-10V. Keeping in mind that I have a well rounded Set of sharpening skills. Advantages: Toughness, edge retention. Thanks to powder metallurgy, youll find even better edge retention on the high end. Which one is right for you? D2 steel does not contain enough chromium to make it stainless steel. I see tables that compare Toughness,Edge Retention,Corrosion Resistance. Ive seen more talk and some articles regarding the use of AI to come up with new potential drug molecules, polymeric materials, etc. Some of these steels also have vanadium (CruForgeV) or tungsten (Blue Super, V-Toku2, 1.2519) for increased wear resistance. There is buzz out there but I havent seen anything solid yet in the world of steel. When describing the characteristics of a steel, a few common attributes are commonly talked about. I can also say from personal experience that marine grade plywood will chaw up your saw blade and battery a lot quicker than standard plywood, but that probably says more about the glue that was used than the wood. In other words, heat treating a steel to its maximum hardness does not necessarily mean reduced corrosion resistance.
