Why can the stainless steel does not rust?

by:Xianke     2020-05-24
Stainless steel has the ability of resistance to atmospheric oxidation, namely, stainless, also has in the medium containing acid, alkali, salt corrosion resistant ability, corrosion resistance, but the size of its ability to resist corrosion was with the chemical composition of steel itself, and each state, using conditions and environmental medium type and change. So not any kind of stainless steel, in any environment ingeneral, corrosion is not rust. Stainless steel plate is formed on the surface of a layer of frozen a very thin and fine and stable solid rich chromium oxide film ( Protective film) To prevent the oxidation of oxygen infiltration, continue to, and get the ability to resist corrosion, once you have some reason, the film has been continuously destroyed and air or oxygen atoms in the liquid iron atoms will constantly infiltration or metal separation out unceasingly, stainless steel forming loose iron oxide, metal surface are also constantly rust. Welcome you the presence! Please baidu: frozen plate, stainless steel instruments, the stainless steel ice bucket
