From Knife Steel Nerds:
I recently got some Vancron steel from Malachi of Troopah Knives and we were able to do some toughness and CATRA edge wear testing. I heat treated all of the coupons and knifemaker Shawn Houston of Triple B Handmade ground the CATRA blades. I had previously a very small amount of Vancron that I was able to do some hardness coupons with but that was the extent of my previous investigations. Vancron is a somewhat interesting steel as it has a very large nitrogen addition (1.8%) though it is non-stainless, along with a high vanadium content of 10%. It is a modification of an earlier steel called Vancron 40 which had higher Mo and W but this resulted in Mo/W carbides that they wanted to avoid. I have a previous article about nitrogen-alloyed knife steels in terms of how they are made and the effects of nitrogen.
