Alloy Steel vs Carbon Steel – What's the Difference ...
D2 is actually a tool steel. This is an interesting one because it has 11%13% chromium, but it's only considered "semistainless". D2 steel will rust more than regular stainless (like the very common 304), but not as much as regular carbon steels. It uses a combination of cobalt and chromium to achieve really high wear resistance.

Why Does Stainless Steel Rust?
Mar 19, 2015 · Stainless steel can contain other elements such as nickel and manganese, but chromium is the key element which makes it rust resistant. When the surface of normal steel is exposed to oxygen, it usually forms ferric oxide (Fe 2 O 3) which has the wellknown red rust color. Ferric oxide doesn't form a continuous layer on the steel because the ...
