Stainless steel reaction with base
Webb23 maj 2024 · Stainless steel is an alloy of N i, C r, F e with other trace elements, and owes its apparent resistance to corrosion to a protective, adherent, coating of mixed chrome, nickel, and iron oxides. A large amount is probably C r X 3 +, which is amphoteric and will dissolve in hydroxide solution. WebbStainless steel is designed to have a high melting point (usually above 600˚C). While it can withstand temperature extremes without melting, this can still affect it in ways that …
