Most meteorites are stainless steel with a nickel % of more than a basic man made stainless of 8%.
I remember one guy that sold slabs had rust problems so I got to wondering if he had a meteorite
or a hunk of iron. Could be that he had a lower % of nickel.
Some meteorite finds are rusty and I've heard said that there would be more found except they have
rusted away. I see by the %, chromium is fairly rare to only a trace %. A nickel chromium with a high %
of both would make an almost indestructible meteorite.
