I’m interested in obtaining a chunk of Russian tank armor, to make some cooking knives out of.
Kind of curious what kind of steel a typical vintage tank is made of. Probably some kind of mid-carbon, given that “spalling” is an issue if the armor is penetrated. It’s probably somewhat hard but not martensitic. Naturally, the fancier tanks have layered armor, such as the US “chobham” armor that is on the M-1 non-export version – that’s got ceramic and a thin layer of depleted uranium in it. I am not interested in finding out how depleted uranium welds.
This thought inspired me to search in a few places, and it appears that military armor is not something that is readily obtained. There’s a sherman tank in Philipsburg not 10 miles from my house; I wonder if anyone would mind. Gun barrels are good steel, maybe just shorten it a bit?
