The Maxamet steel in considered as a “Super Steel”, So it’s a High-end Alloy steel, with an uncommon chemical composition, but I can say that the closest one to it is the CPM S110V(even if it’s stainless steel), in exception of wear resistance; the Maxamet is a great match for the S110v in edge retention, hardness, wear-resistance and price range which is between 100-200 Usd. $200.00. The Mule Team was set up with identical knife blade blank designs in different steels in an attempt to compare apples to apples when testing the knives. Not as sharp as steels like AUS8, but pretty sharp. Chromium carbides are softer than vanadium carbides and therefore contribute less to wear resistance. $160.00. With S110V having quite a bit of each of those elements the steel cannot be fully hardened when it has no cobalt in it. What is its hardness? I have not had hardness testing done on the S90V or S110V, only on the Maxamet, but I assume that Spyderco has a similar hardness level in both S90V and S110V. I prefer the S35vn blah on the LW scales. Pacific Salt™ 2 Black Blade. Here is the datasheet. Instead, the inventors of S110V used cobalt, which is an austenite stabilizer at high temperatures but does not increase retained austenite when quenching to martensite, unlike Ni and Mn. I'm still curious to see a custom knife made out of Maxamet though. In an alloy, Tungsten contributes to the harden-ability, and with this much Tungsten it’s no surprise that Spyderco hardened Maxamet up to 67-68 RC. Wear Resistance: the wear resistance is excellent, due to the Tungsten, Vanadium, and Carbon, the Maxamet offers a great wear resistance. $217.00. They have the same blade grinds, and they are heat treated and processed by the same manufacturer, of course. However, S90V and the modified S110V (labeled 11V) have 11.5% Cr in solution while S110V (9Nb-3.5Nb) has 12.3% Cr in solution, which would provide better corrosion resistance. P'Kal™ G-10 Black. What austenitizing temperature did you use? You’ll pay for it though, at roughly 1.5x the price. So if you intend to use in humid environment, you better take care of your knife, other than that it’s a great steel of an EDC knife. S110V is designed to be heat treated between 2050 and 2150°F so the steel would need to be austenitized in that range. electroslag, forged ring/ … In my original edge retention article I speculated that perhaps the smaller carbide size was the difference and I made some comparisons with the size of the abrasive particles used in the testing. Maxamet is a powder steel from Carpenter, an American steel company. However, niobium is a “stronger” carbide former than vanadium, meaning it can form niobium carbide even in the presence of high amounts of chromium. There are other elements that can stabilize austenite as well, notably carbon, nickel, and manganese, though those elements also increase retained austenite. Maxamet is a powder steel from Carpenter, an American steel company. S110V's data sheet mentions, for example, that it has better corrosion resistance than S90V. If you’re looking for an EDC knife with a Maxamet Steel, the NATIVE 5 is your choice. $145.00. That sounds low to me though I haven’t used JMatPro in the past to predict retained austenite. Von Gesichtsrasur war ja ausdrücklich nicht die Rede. As a rule, the harder the steel, the easier it breaks, so the Maxamet steel is very hard steel that can break very fast, but it’s tough enough to handle some beating, damaging work. The reduction in Nb may have led to the other changes in the steel. Both of these steels are a real bear to sharpen up! For example, S30V had increased Mo over the earlier S90V/S60V for improved corrosion resistance, and that trend continued thereafter with other Crucible products. My edge testing shows how various steels retain absolute sharpness at the fine cutting edge vs man made materials, in this case, fibrous rope. This isn't a knife to beat on or put any lateral pressure on. Spyderco Military Left Hand Black G10 Plain Edge Satin C36GPLE . Whether this was due to a problem that was observed in production or simply being cautious I am not sure. P'Kal™ G-10 Red Trainer. Von Gesichtsrasur war ja ausdrücklich nicht die Rede. the effect of cobalt on raising martensite start temperature inspires me an idea . Sie ist lediglich nicht mehr fein geschlossen. Spyderco Military Left Hand Black G10 Plain Edge Satin C36GPLE . They have the same blade grinds, and they are heat treated and processed by the same manufacturer, of course. $310.00. There is another aspect of S110V vs S90V that I would like to mention. Although Maxamet isn't stainless, but at the same time Maxamet is tougher compared to Crucible CPM S110V steel, which can result in better edge holding ability, and cutting performance with the right geometry and heat treatment. S110V has a finer carbide structure than either S90V or S125V. Combined, these features offer a distinctive look and exceptional edge geometry. So sharpening these knives to a keen edge with ceramic involves crushing those carbides (near the apex) into “nano-dust” and burnishing the matrix around them. Both of these steels are a real bear to sharpen up! Although Maxamet isn't stainless, but at the same time Maxamet is tougher compared to Crucible CPM S110V steel, which can result in better edge holding ability, and cutting performance with the right geometry and heat treatment. Try as I might, I can’t get S110 to push cut paper at right angles. If there is any steel in Crucible’s line up that is likely to inherent the mantle of “awesome all around performer” from S35VN (which, in turn, took it from S30V), it will be this steel (or one yet released). Go buy one for yourself, and everyone you know, as a Christmas present. Few steels can approach this level of hardness while remaining usable in cutlery applications. maybe if alloyed with niobium carbide the hardness will be raised somewhat . If you are unfamiliar with the Para Military 2, this will help you get a better understanding of one of the most popular knife designs in the past 10 years. S110V and S90V are my favorites in the very high edge retention stainless steel category, depending on the level of corrosion resistance that is necessary for the application. Auch von einer Ruinierung der Schneide kann nicht die Rede sein. I will use “0888” and “0888MAX” interchangeably throughout this article except for when specifically discussing the steel below. (This is not heat-related). It's cool to carry a knife made from Maxamet, M390, or CPM-S110V. And other questions). $305.00. In Stock . In an attempt to clear out some of my unused knives, I’m putting up some of my Spyderco Mule Team blades. Read more about niobium additions in this article. Es hatte geheißen, daß Armhaare nicht denkbar seien. However, as explained above with S90V, balancing vanadium and chromium is challenging to obtain a high combination of wear resistance and corrosion resistance. Maxamet ist der neueste Pulverstahl von Carpenter (auch bekannt als CarTech). Therefore, I see the main choice being between S110V and S90V for best very high edge retention stainless. Typically instead the steel designer increases the level of carbon to the point that the steel can be austenitized. With that said, the difference between the 2 is that the 0888 is uncoated and comes with a composite S110V and 14C28N blade, while the 0888MAX is black DLC coated and approximately half of the 0888MAX knives feature Maxamet steel, and the other half have M390 steel bl… But S30 at least eventually gets sharp, S110 never does (for me). Es hatte geheißen, daß Armhaare nicht denkbar seien. Become a patron and gain access to awesome rewards including early access to articles or a Knife Steel Nerds mug! $250.00. If you’re interested in the Maxamet steel for your knife, and still have doubts, I would like to assure you that’s it’s a great steel for your knife, depending on your usage, its has an exceptional edge retention and excellent wear resistance, but it’s low on corrosion resistance, so if you’re an EDC user (you like to have a tactical knife on you, for opening boxes and canes or whatever your bare hands can’t handle) it’s a great knife for you! The Maxamet steel in considered as a “Super Steel”, So it’s a High-end Alloy steel, with an uncommon chemical composition, but I can say that the closest one to it is the CPM S110V(even if it’s stainless steel), in exception of wear resistance; the Maxamet is a great match for the S110v in edge retention, hardness, wear-resistance and price range which is between 100-200 Usd. But, If you’re a Diver, Hunter, Kitchen Chef, or you use your knife in humid places, and you’re looking for premium steel, I wouldn’t recommend the Maxamet I would instead go for the S110V stainless steel. Somewhat surprisingly, they both resulted in identical toughness despite the higher austenitizing temperature leading to higher hardness. With increased Cr in solution, but decreased Mo, it is not clear which version would have superior corrosion resistance. Native® 5 G-10 Dark Blue CPM S110V. The carbide volume of S110V is closer to S125V which is significantly coarser. However, a version of S125V with 2.7% Mo was in the S90V patent, which predated S30V, so it isn’t 100% clear in which direction inspiration occurred. The standard blade steel of the Native 5 is CPM S30V stainless steel, but Spyderco has expanded that offering with additions like super high-grade CPM-S110V and Maxamet steels. This was confirmed in tests reported in the patent, where a cobalt free version had some ferrite present after heat treatment, and only reached about 54 Rc. FYI the maxamet manix is a lightweight without liners and is pinned. However, more carbon means more carbides which reduces corrosion resistance and toughness, as described in this article. They have the same blade grinds, and they are heat treated and processed by the same manufacturer, of course. The cobalt content was increased from 2 to 2.5%, likely based on updated estimates of how much austenite stabilization is necessary after the changes to Nb, Cr, and Mo. Model # SP-C81GPDGY2 . The results can be seen below. However, what is surprising is that it did worse than S90V. So sharpening these knives to a keen edge with ceramic involves crushing those carbides (near the apex) into “nano-dust” and burnishing the matrix around them. TWISTED SISAL MERCH - THANKS TO MISHEARDKNIFEREVIEWS: https://teespring.com/twisted-sisal-merch Remember to subscribe for more lunacy - hit the bell etc! That article explores a lot of aspects about cobalt because there isn’t much of a good reason to be in VG10 at all. Und das ist definitiv falsch. In fact the revised datasheet shows all of the same data for corrosion resistance, hardness, and wear resistance despite the fact that the change in composition was relatively substantial. All of the following experiments were performed on the later version of S110V, as that is all that is available to purchase. Native® 5 FRN Pink. My edge testing shows how various steels retain absolute sharpness at the fine cutting edge vs man made materials, in this case, fibrous rope. Where a steel like S30V really shines is in sharpening. With S110 you have to battle burrs just like S30. I have 3 spyderco Native 5’s in S110V, S90V and in Maxamet. adding niobium carbide “if all regarding problems solved” to this steel can push hardness/edge retention to a very high numbers . I then calculate Ms and plot vs hardness to see where hardness starts to drop from excess RA. Model # SP-C81GPDGY2 . This will be relevant to the toughness discussion later on. S110V and M390/20CV/204P do have higher Cr in solution than S45VN. This is exactly why I don’t evaluate production knives to compare steels. This might be happening because the knives are from different manufacturers, using different heat treat and blade grinds? In my original corrosion resistance experiments with 1% saltwater I found S110V to have very good corrosion resistance, certainly a significant upgrade over S90V and S125V, and being similar to M390, another grade with very good corrosion resistance. This is the only example of using cobalt for this purpose in a stainless tool steel that I am aware of, and is one of the biggest innovations of S110V in my opinion. Native® 5 Salt® $186.00. Spyderco Paramilitary 2 vs Benchmade Griptilian : It’s no secret the Griptilian is one of my favorites but overall the PM2 is simply a better knife. Even with that handicap, it’s a great knife. Native® 5 G-10 Black. CPM-S110V. P'Kal™ G-10 Black. To look at this difference I used ThermoCalc to estimate the amount of carbon, chromium, and molybdenum in solution with S90V, the patent version of S110V (2.8C-14Cr-9V-3.5Mo-3.5Nb-2Co), and then a modified version of S110V which has 11% V instead of 9%V-3.5%Nb (2.8C-14Cr-11V-3.5Mo-2Co). All PM2s are great at EDC tasks. Sharpening them all on diamond resin stones, and stropping with diamond paste on leather ends in a hair whittling edge on all 3 knives (including the S110V). Understand that a keen edge requires a dimension of around 100nm (1/10 of a micron) and the vanadium-rich carbides in Maxamet, or S110V, or even the chromium carbides in ZDP189 are 1-2 microns in size. I can get the S90 much sharper than the S110. Spyderco ParaMilitary 2 Dark Gray G10 Stonewash Maxamet C81GPDGY2 . I do emphasize with the guy who chipped his blade, but I do find Maxamet to be less fragile than S110V. For reference, steels like S110V and ZDP 189 are taken up to the low 60s (maybe as high as 65 for ZDP-189). $265.00.
