But among the steels youll find at Cabelas and the like, this is a pretty good choice. The line is only in the neighborhood of 5 of the datapoints. The steel is susceptible to overheating during hardening do not overheat. blue steel Sandvik 14C28N steel is better than D2 steel in corrosion resistance and toughness. Any idea where it would be on the hardness and toughness scales? CPM 10V Both of those things are no longer an issue as I now have way too many articles and a book. . 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.
can you strike twice as fast with the knife? But Ive found it lacking in hardness, even when compared to cheaper steels like AUS-8. A Japanese powder steel, ZDP-189 is essentially the polar opposite of 3V its uber-hard instead of uber-tough. I have the average composition of the steels rated above (plus some extras) so you can see what the different names refer to. There is a powder form, CPM-D2, and PSF27 is also very chemically similar. The D2 version is heavier and harder, but doesn't cut as smoothly. YMMV Thanks for the Article Larrin, GearJunkie Copyright 2013 2023. If you're stuck between 14C28N and 440C, here's a breakdown of the pros and cons of each type of steel. Oftentimes steels that are reported to be difficult to sharpen are in fact improperly heat treated and challenging to deburr. Read more about how it works here. Read more. Below shows the results of MagnaCut testing vs other steels where it is labeled as New Steel.. So for most steels they are given a rating at around 59-62 Rc, apart from a few steels that are never used at that hardness. 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. If you purchase this types of knife, without any hassle you can easily re-sharpening. The main downside is the steel is more difficult to heat treat and can't go harder than about 60 or perhaps 61 Rc. If you want to learn more about a specific steel, you can click it in the sorted listings below. It would be really useful to have the raw data that backs the charts that you produce. Sorry, most of my previous comment was borderline word salad. . 2. See the chart below showing 52100 steel that was overaustenitized (unintentionally) by a knifemaker that sent me specimens for toughness testing. 14c28n steel has a high Chromium and Carbon percentage. 8cr13mov if proper slicing geometry its good budget steel if you dont rust it and no prying or screwing its ok cutting steel. 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. Hello everyone I've been loking into twosun knives recently. Tougher than D2, but less wear-resistant. The hardenable grade of titanium (Beta C Titanium) reaches up to 45 or so rc. PESR would be an interesting topic too (also tied to LC200N). How do its properties compare to other steels? 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. The reason is because sharpening and edge geometry will also greatly control properties. The D2 steel compares nicely with 14c28n steel in terms of edge retention, as it's quite hard as well. Below shows charts summarizing tests of different steels for the major categories discussed so far, low alloy steels, high alloy non-stainless steels, and stainless steels. 1. also the angle is by far the most important factor in catra testing, so such results might be irrelevant. When describing the characteristics of a steel, a few common attributes are commonly talked about.
I also added a few more steels in this study. Thats a little too far, but you get the point.). Chris Reeves version, which is about two points less hard than others, is quite good. There seem to be a lot of modern steels that get related to D2, but OTOH just saying a steel is similar to D2 seems to kill interest in it. AEB-L and 14C28N also have moderate edge retention though of course much lower than vanadium-alloyed powder metallurgy steels like S30V or M390. That says to me theres a measurable abrasive quality to wood for sure. Its actually quite good, low-cost steel that performs like midprice steel. I tested its edge wear resistance but not its toughness yet. Can you contact me via my email address so I can send you a copy in PDF and epub. 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. He is the mind and writer behind Knife Steel Nerds, the go-to source for all knowledge about knife steel. Theres still a lot of misinformation being pushed by influencers especially in knife steel rankings. 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. the following is not a critique, just a few thoughts to maybe put the relationships into a wider perspective and point to additional dimensions. are after the ratings. I see tables that compare Toughness,Edge Retention,Corrosion Resistance. thanks thats interesting. EDGE RETENTION . Some steel companies charge more than others. But its very cheap, and, when ground appropriately, it can be a real winner from a value standpoint. 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. This is a midprice steel with matching performance. SG2 But in my experience, it has been nothing but great. 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. Combination of knife steel properties. The stainless steel rating. A proprietary steel and heat treat developed by Busse Knives, INFI is an excellent performer and one of the best steels for big choppers on the market. HAP40 and corrosion resistance than the 420HC steel. Thanks again for everything you're doing, it's a tremendous resource. Here, we break down how to choose a flashlight, including best flashlight LEDs, batteries, designs, and more. The edge retention numbers are normalized to the hardness of the closest toughness test. It would be interesting to try to develop a conversation between /geometry/edge retention/toughness, so we could say e.g. The blackwashed D2 steel blade of the Kershaw Cannonball offers pretty good corrosion resistance for D2. My name is Jonathan M, and Im a passionate Mechanical Engineer, a knife enthusiast, and the author of this website.
A more obtuse edge angle is much more resistant to chipping than an acute edge. But if you want to know what the coolest blade material is, for my money, SM100is it. On the other hand small but mighty, the pocket knife provides both in professional performance and in arresting good looks. Corrosion on knife steels most usually takes the form of rust, patina, and staining. As wear resistance is increased the differences between conventional and powder metallurgy steels become greater. The Vargo Sobata 398 is unlike any other knife on this list. 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. What makes 1.4116 such a bad performer in regards to toughness on par with ultra high carbide steel like S125V? It mainly made for knife and it high in Chromium for excellent corrosion resistance. They were two different tests (different batch of steel, different person heat treating, etc). 1. If you are a newbie, sharpening D2 knives will be a struggle, but it is doable with practice and the right sharpening tools. We should be suspicious of anyone who is claiming very high edge retention with a steel at low hardness and a small amount of carbide. They are usually chosen for their looks rather than performance. In its most basic form, steel is just iron and carbon, but people have been studying, experimenting with, and perfecting steel with other elements for specific applications for millennia. Having 1.5% Carbon does that. and yet millons of knives are being made out of 1.4116 (aisi 420mov?) 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. 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. Choose a factor below to start sorting. CPM 3V Hi Larrin Your estimate of 420HCs corrosion resistance is different here than in your October, 2019 post on corrosion resistance testing: https://knifesteelnerds.com/2019/10/14/corrosion-resistance-testing/ Read our full Sobata 398 review here. This is one of the fundamental tradeoffs in steel. 12C27 Both steels are popular among knife manufacturers and both have their strengths and weaknesses. 14c28n vs D2 Steel. 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. Therefore, if your priority is a knife with the best toughness on the market, you can never go wrong with the varieties of 14C28N. Steels that are improperly heat treated have excess retained austenite which makes them extremely difficult to deburr. Its so high in hardness that Maxamet knives usually ship with desiccating packages. This guide explains important features to consider when buying a new knife for the outdoors. Vanax and LC200N are unique in reaching 59-60 Rc while being very stain resistant. 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. If I made some plane irons from AEB-L at 63 Rc (where its still tougher than 1095 at 59-60 Rc, the standard vintage steel in plane irons), could I drop my sharpening angle from 30-35 to 25? 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. 52100 and CruForgeV are good for general purpose knives. Its not bad, but you can find better in the market at the same price.
Quick-reference guide: Know your knife steels - KnivesShipFree One argument I see consistently leveled against 8Cr13MoV compared to AUS-8 is that of the consistency of the composition. The material increase machinability and strength. For example, Bohler M390, CTS-204P, and CPM-20CV are all nearly identical and indistinguishable in practice. Its not a regression line, it is just a line through the best steels. SPY27 Because of their good edge retention, these steels are quite versatile in folders and fixed blades. I forgot, I got the higher carbon steels will have higher edge retention from this website. Its called memory metal because heat can get it to revert back to a previous shape. The most balanced is CPM-MagnaCut which is in an area all by itself on the chart. Steels do come at various price points, however, depending on the cost of producing them and the cost for the knife company to work with them. then you have zirconia and diamond coated blades. You cant look at only the chromium content of the steel to know the level of corrosion resistance. Its found on a large number of traditional-style folders. In all of the cases above, properties are greatly controlled by carbides. Many knife enthusiasts are concerned with categorizing steels as excellent, good, poor, etc. Obviously Ill let you check the manuscript prior to publication. While higher hardness does lead to improved edge retention the bigger reason to have higher hardness is for resisting edge deformation. 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. Cold Steel still uses VG-1 on some knives, and, for the money, it does well. 1060 Fix-It Sticks Compact Ratcheting Multi-Tool Review, Toughness, Wear Resistance, Corrosion Resistance. Therefore, ensure to wash and dry your knives after use to keep the rust away. I especially appreciate the geometry/edge retention/toughness comparison with photos. 440B The table shows combinations of knife steel properties for different classes of steel. All three of these steels havechromium, molybdenum, vanadium, and tungsten components and will perform well in myriad tasks. Its an anomaly in the knife world and quite puzzling to use. Also many hardwoods will dull planer blades just because theyre more dense. you can easily buy a $500 knive made out of 14c28n, which has nothing in it besides cr and a trace of ni. What about K390? We use a subsize, unnotched chapy test with 2.5 x 10 x 55 mm dimensions. However,M390, CTS-204P, and CPM-20CV are all pretty difficult to resharpen, so maintain that edge! 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). We all have our preference, but overall, preference leans towards the pocket knife with a clip.
The Best D2 Steel Knives And What Makes Them Great 12C27 steel is extremely popular in the US knife market for its high hardness, high wear resistance, and great corrosion resistance. If you need something that soaks up abuse, try 3V.
All about 14C28N Steel - HDMD Knives Blog Different types of knife steel Alleima I have a Winkler Knives Recon model in 5160 steel and even though the knife model is ok, the steel is shit. Thats a pretty large difference in two budget steels that are often compared to each other. The Sandvik 14c28n steel is ideal for the manufacturing of steel knife blades. 440C steel 14c28n is the most popular material for the knife: stainless steel and made by the Swedish company. Poor heat treatment can make a knife too hard, too soft, hard to sharpen, easy to deform, or cause other issues. Below, weve listed some of the attributes you might want out of your steel and given some examples in both the more expensive powder metallurgy steels and more affordable conventionally produced steels. This is also a powder-metal steel produced by American steel company Crucible. Below shows approximate maximum hardness vs stainless rating for several stainless knife steels. I personally don`t care about stainless (sic! And while youll find it mostly in expensive knives, quite a few approachable M390 blades exist. 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. just recently the idea occured tome to sharpen a planer blade like a knife and check out how it performs. Im going to give the ratings first and then give more explanation about how the ratings were created. Are you okay with that? as you mentioned catra indicates the edge angle as being by far the most important variable. 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. It also improves edge retention and strength. 14C28N steel is as a result of a more corrosion resistant version of the 13C26 steel. 2. The biggest factor for cost of knife steel is whether it is produced with conventional ingot technology or powder metallurgy. That said, it's not as tough as many other steels and exponentially tougher to sharpen. These steels are perfect for thin edges and high hardness. Im not hating on 80crv2 , Ive used it. When the blade gets messed up I just replace it. There are also hardness/toughness and hardness/TCC charts.but no tables backing this charts. 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.
14c28n vs d2 - Which Model For Best - Knifeyellowpages 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. Finally, in this 14c28n vs d2, we hope you get the right one. Around 61 Rc usually. This refers to the angle of your edge and the thickness of the knife behind the edge. 14C28N knives are better than D2 knives in corrosion resistance. 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. 14c28n has less carbon and chromium as compared to 9Cr steel. The excellent corrosion resistance properties of 14C28N are attributed to the high amounts of chromium in its composition. In this article, we will discuss the characteristics, pros, cons, and differences between 14C28N and D2 knives to help to make the right choice. Many steels are very similar to one another but go by different names from different manufacturers.
Knife Steel Rust Testing 1095, 8Cr13Mov, D2, 420HC, Walmart - YouTube Im not sure they answer my question, though, and some of your points dont seem to jive with the info here on Larrins site. For example, below is a video comparing a 1095 ESEE knife at 55-57 Rc and a MagnaCut knife at 62.5 Rc, both with the same edge angle. Manage Settings For more information, please see our In thick forms, like a fixed blade, 1095 isa tough, low-cost steel. European steel company Sandvik produces 14C28N, a non-powder metallurgy steel. Most of the midrage ifferings have 14c28n, how does it compare to d2 in your experience? Goes to show that science not marketing or conjecture is what determines a good steel, 51shitty? This can turn the ultra corrosion resistant LC200N or Vanax into a normal stainless steel that will rust with only 1% saltwater. Often used for combat knives. Powder metallurgy steels with low vanadium content like CPM-1V and Z-Tuff/CD#1 have extremely high toughness. Monday-Friday Spyderco has their own salt spray test setup to determine the corrosion resistance and they determined that MagnaCut is sufficiently corrosion resistant for their salt series of knives. Knife steel nerds have a great write up on 14c28n nik_was 2 yr. ago 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.. 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. The best scenario is when the steel, heat treatment, and geometry are selected for the knife and the use. 14C28N VS D2 Attributes: 14c28n: D2 . Jesse Jarosz, a custom maker from Montana, regularly uses AEB-L. The critical difference between these two sheets of steel is their corrosion resistance. Steel with high wear resistance is more costly to manufacture, as the knife company goes through more abrasives to grind the knives. in relation to hardness). Rex 121 23.5% vanadium carbide, 4% molybdenum/tungsten carbide (M6C), Conventional Ingot vs Powder Metallurgy Carbide Structure. The edge retention and ease of sharpening have been what we expect with D2. 14C28N is offered on midprice knives and is one of the better steels on a dollar-for-dollar basis. Thank you for such a great article! D2 is a tool steel used in industrial settings.
How Good Is Nitro V Stainless Steel - Knives & Gear 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. I believe they are made of simple carbon steel. Cookie Notice I see very little about cryo outside of journal articles, and I wonder which knifemakers use it. I have a few examples below for steels that I have ranges of hardness tested for both toughness and edge retention. 1% saltwater will separate between other stainless steels. Dr. Thomas is a friend of ours here at Blade HQ, and with his help, weve worked to create this knife steel guide. The hardness level of steel is determined using a universal scale called the "Rockwell C Test", commonly called the Rockwell hardness scale (HRC). I love reading through all the data youve gathered and making note of all the trends (Im a physical organic chemist). All of the experiments shown below are possible thanks to supporters. SUS410 D2 is a high carbon, high chromium die steel and is the highest carbon alloy tool and die steel typically used in knife making.
Also Mo additions improve corrosion resistance for a given amount of chromium. Find your right answers here! Then we could say, e.g. Aluminum oxide is used in most common sharpening stones and it is softer than vanadium carbide, which makes sharpening high vanadium steels more difficult. Toughness is the resistance to chipping or breaking. 14c28n is the most popular material for the knife: stainless steel and made by the Swedish company. show very different and even inversed behaviour (e.g. worldwide, even the chinese have an equivalent (8cr13mov). 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.

The chart below has dotted lines which indicate the average effect of hardness for any given steel. An example of data being processed may be a unique identifier stored in a cookie. If thats true why do you include it in the stainless steel category? 14C28N steel is the improved version of 13C26 with better rust resistance. And we list budget-friendly knives that have a professional style and grace to them. Though technically not a stainless steel at least 14% chromium, and D2 usually has 12% its relatively corrosion-resistant. Three main characteristics differentiate steels from one another: corrosion resistance, hardness, and toughness. . This is an American-made powder steel. The only thing putting me off immediately buying the p135 is the 14c28n steel. CTS-204P and CPM-20CV are nearly identical steels made by other manufacturers. The brand Bark River uses A2 in many models. https://knifesteelnerds.com/2018/12/17/cryogenic-processing-of-steel-part-3/. 14C28N is a type of high-performance stainless steel used in knife-making. More expensive powder metallurgy steels in this category include M390, CPM-S35VN, Elmax, CTS-XHP, CPM-S30V, and CPM-154. CPM-3V is a powder metallurgy contender in this category. S35VN 8670 and 5160 are good choices for large knives that need very high toughness. Note that corrosion is detrimental for the cutting edge. It can withstand a lot of wear and tear. Is 440A really that much better than 420HC, or have you found a narrower gap? Larrin, thank you for this. Most of these steels are carbon steels, except for CPM MagnaCut (the fancy steel cooked up specifically for knives by Dr. Thomas), which has excellent corrosion resistance. 14c28n vs. D2 Steel D2 is as rigid as 14c28n, thus has almost equal edge retention abilities. Not to sound like a ship, but these two knife inspiration makes this an eye-catching knife. Sure if you dont want stainless steel fine, but there are plenty other carbon steels out there much better than 5160. While not a powder steel, 154CM is widely used in nicer knives. Is Vancron SuperClean a good choice for a chef knife? Importing steel from Europe to the USA, or vice versa, generally increases the cost. Toughness and edge retention are generally opposing properties and it is difficult to improve both of them at the same time. Its very corrosion-resistant and quite tough. Moreover, the blades will serve you longer because they do not wear out faster with frequent use and sharpening. Here its 8. What it is: D2 is a carbon tool steel with a relatively high chromium content, prompting some to call it a "semi-stainless" steel. Micarta In nitrogen steels, nitrogen is used as the iron-hardener instead of carbon, thus limiting the possibility of rusting. Been here before? 1.4116 There is no single category that means that a steel is more premium or better than another.
Knife Steels Rated by a Metallurgist - Toughness, Edge Retention, and It has excellent edge retention, corrosion resistance, and ease of sharpening. This is a virtually stain-proof steel suitable for all sorts of aquatic environments. my understanding is that wood is not a particularly abrasive material and a plane is more of a push cut action than a slicing action so I would have though edge stability and sharpness is more important than edge retention meaning ABE-L should work pretty well. These images are taken from my book Knife Engineering. 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. 14C28N is the highest-selling steel of Sandvik, a Swedish steel company. Different heat treats have emerged over the years, but one has risen to the top as the best:Bob Doziers D2. 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. This is especially important for chopping knives and for knives with thin edges for enhanced cutting ability and edge retention. The both blade are equally wear resistant. And while it can be hard depending on the heat treat, I have found it easily chips, causing microscopic dings in the edge when hardened to a high level on a thin blade. Thanks! This isnt exactly how steel works; different properties are difficult to increase without affecting something else.
