Plus stainless often leaches chromium and nickel but it subsides with time.
Much of the 304 stainless the Chinese sell is not 304 as it rusts and pits.
Stainless steel doesn’t “leach” Cr and Ni. Yes, there is some short range Cr diffusion at the surface to form the protective oxide layer. If you scratch SS and immediately put it in a salt water environment, it will rust. Pitting occurs from a type of galvanic corrosion and can occur on “real” SS given favorable conditions.
