now, alloy steels are a different story, they're made by adding in stuff to carbon steel, usually some manganese and sometimes chromium (for stainless steel) or vanadium

Nickel is added into a lot of steel smelts to increase the strength of it.
I hate it, but that's because my job is to turn, drill, and bore into different kinds of steel, and the more nickel in the alloy, the worse time I'm going to have!
oh stainless also contains nickel
