May 13, 2020 #13. In the article I wrote about nitrogen-alloyed steel I focused primarily on nitrogen “in solution” which increases hardness and to some extent corrosion resistance. However, the datasheet has an asterisk next to the 143% value and says that it is “based upon market feedback.” These estimates should perhaps be treated with some suspicion as the S35VN datasheet has the same asterisk for its 145% value which puts it at the same level as S30V, but independent experiments put S35VN around 132% at 61 Rc [8]. Does a higher heat treatment reduce s45vns corrosion resistance? S45VN pm2 (A) never cut, used, carried slightly off centered $170. Everyone loves a Gunny! If you buy 2, you will get a bar that is 24" in length. You can read more about cryo treatments here: Part 1, Part 2, and Part 3. I extended the austenitizing temperature above the recommended range in the datasheet (1900-2000°F) because of prior experience with heat treating S35VN. So I would choose S45VN for higher edge retention and corrosion resistance and S35VN for better toughness, depending on your desired properties. But there are going to still be much better steels for the job in regards to folding knifes. But if the edge should get dinged or dulled against bone, all you need to do is mail it in to Benchmade’s popular LifeSharp Service. It also boast nearly the toughness of s35vn. CPM® S45VN is a martensitic stainless steel specifically created to transcend its predecessors. I wouldn’t say that S45VN is any more sensitive to heat treatment than any other steel.

The following chart shows C and Cr in solution for a range of PM vanadium stainless steels using ThermoCalc estimates with the recommended austenitizing temperature found in each datasheet: I heat treated S45VN by wrapping it in heat treating foil and heating it in an Evenheat furnace. Vanax has higher toughness than S45VN, being similar to S35VN when adjusted for hardness. Blade Hardness: 58-60 HRC. S110V has a similar Mo content as well so it should still have better corrosion resistance than S45VN. So was crucible’s intentions to produce a higher mid ranged steel? I found that the carbides were significantly finer by using the 2000°F austenitize which is a likely explanation for the improvement in toughness: While austenitizing temperature does lead to the dissolution of more carbide, this does not always lead to an improvement in toughness because grain growth is possible and with more carbon in solution there is a chance of embrittlement. S35vn has been being put into high end folders ($300-700) Chris Reeves, Sparta blades ect…, and I don’t understand the reasoning, That shift in favored carbide types improves wear resistance by having more of the harder vanadium/niobium carbides (MC) and also improves corrosion resistance because less chromium carbide (M7C3) is formed: In the article about niobium additions, I wrote about how niobium is a stronger carbide former than vanadium, leading to hard niobium carbides even in high chromium steels. PLUS, it’s easier to grind and sharpen then either. Lol. CPM-S45VN steel for improved wear resistance and corrosion resistance : ... Bark River Knives: Petty Z - CPM S45VN. see all.

This has all been on my mind for a good amount of time. Powder metallurgy steels generally have at least 0.05% nitrogen in them from pickup from the atmosphere and the nitrogen gas atomization process [2]. S45VN shows improved toughness and corrosion resistance relative to S30V along with similar edge retention. As noted in the niobium article, small additions of niobium can also improve toughness by refining the microstructure as a whole by changing the sequence of solidification. However, nitrogen can also be intentionally added to the steel for higher amounts. The increase in Cr in solution puts S45VN at a similar Cr-level to Elmax, but it is still somewhat below S110V and M390. S45vn boasts higher corrosion resistance vs both. Leather sheath included. So…they took the good attributes of each steel and made s45vn. The knife is with a hidden tang.
