What is the coating on stainless steel that makes it "rust proof

Stainless steel ordinarily needs no coating. The main element alloyed with iron to make stainless is usually chromium. I believe that stainless steel forms a thin oxide layer, but it contains enough chromium to avoid forming the flaky oxides (írustí) that form on pure iron, so the oxidation doesnít keep going.
