Why is stainless steel rust proof?
First I think you need to know about Rust and Stainless Steel , so read this. http://en.wikipedia.org/wiki/Rust http://en.wikipedia.org/wiki/Stainless_s… Why doesn’t stainless steel rust? Nancy Avery, New London, Conn. Metallurgical engineer Michael L. Free of the University of Utah offers this explanation: Stainless steel remains stainless, or does not rust, because of the interaction between its alloying elements and the environment. Stainless steel contains iron, chromium, manganese, silicon, carbon and, in many cases, significant amounts of nickel and molybdenum. These elements react with oxygen from water and air to form a very thin, stable film that consists of such corrosion products as metal oxides and hydroxides. Chromium plays a dominant role in reacting with oxygen to form this corrosion product film. In fact, all stainless steels by defini
