In previous corrosion testing I performed, I found that the effect of Mo topped out at a certain level, but it would be surprising if Crucible also came to a similar conclusion. The 11V steel would still be an upgrade over S90V for corrosion resistance because of the higher Mo in solution (see the Molybdenum section later on in this article). Maxamet ist der neueste Pulverstahl von Carpenter (auch bekannt als CarTech). S90V was patented around 1996, the major innovation over previous steels was a reduction in Cr down to 14% which led to the formation of more vanadium carbide for a given amount of vanadium. In this section, we’re going to compare our steel with other steels, and for this, I use four criteria; Edge Retention, Corrosion resistance, Ease of Sharpness, and Toughness, and I use a scale or note from 1 to 10. Die Zähigkeit ist angemessen hoch, jedoch auf Kosten der Korrosionsbeständigkeit (nicht rostfrei). Niobium carbides are very small when used in powder metallurgy steel, and can also help decrease the size of chromium and vanadium carbides in the steel as described in the niobium article. electroslag, forged ring/ … A similar comparison was made in the patent, as 11% V is roughly equivalent to the V-Nb combination in S110V. However, as explained above with S90V, balancing vanadium and chromium is challenging to obtain a high combination of wear resistance and corrosion resistance. The reduction in Mo from the original version (3.5%) to the final version (2.25%) likely means that these values are no longer accurate. Para™ 3 G-10 Black/Black Blade. This will be relevant to the toughness discussion later on. One of the best knives you can get if you’re looking for high-quality steel and premium design, the NATIVE 5 is a beast that combines strength, superior cutting performance, edge retention, and point utility it comes with a grey, injection-moulded reinforced-fibreglass-nylon handle, the Native 5 has a back lock mechanism and a four-position pocket clip, which makes it very comfortable and efficient. Manufacturing Technology - MM. That said, S30V is a great steel! If more corrosion resistance is required then S110V is the way to go. S110V has somewhat more carbide than S90V, making it even more impressive that the carbide size is finer. S30V is not in the same wear resistance class as the other steels, but the design of that steel may have influenced the others so I included it. Native® 5 G-10 Black. $217.00. So there is a maximum amount of niobium that can be used before this happens, somewhere in the 3-4% range. So it could be that S110V has similar toughness to S90V, but also recall that the 2050 condition led to lower hardness with no improvement in toughness. S90V offers somewhat better toughness and edge retention making it more balanced for applications that need only medium corrosion resistance. The Spyderco Para Military 2 - What more needs to be said? With S110 you have to battle burrs just like S30. One change to S110V was a reduction in Nb from 3.5% to 3%. I haven’t performed a full range of heat treatment experiments on S110V, but comparisons with S90V show the two heat treating relatively similarly. Spyderco Military Left Hand Black G10 Plain Edge Satin C36GPLE . 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. This might be happening because the knives are from different manufacturers, using different heat treat and blade grinds? I then calculate Ms and plot vs hardness to see where hardness starts to drop from excess RA. The Griptilian is comfortable but it feels totally different in your hands versus the PM2. S110V is designed to be heat treated between 2050 and 2150°F so the steel would need to be austenitized in that range. The s110v blade of this Manix 2 blurple is very very sharp so be careful with it. If you find trouble understanding the meaning of hardness or HRC, here you can find a blog post explaining it. Sie ist lediglich nicht mehr fein geschlossen. And other questions). The patent for the steel was first filed in 2006 by inventors Alojz Kajinic, Andrzej Wojcieszynski, and Maria Sawford, all of Crucible Steel.
