The reason why stainless steel has excellent corrosion resistance is mainly due to the passivation film formed on its surface. This passivation film is an extremely thin and strong oxide layer formed by the reaction of chromium and oxygen, which can prevent oxygen and moisture in the external environment from directly contacting the metal matrix. When the film is damaged, the chromium element will quickly react with oxygen in the air again to restore the passivation state, thereby maintaining the corrosion resistance of stainless steel. In order to further improve the corrosion resistance of stainless steel, it is also common to add elements such as nickel and molybdenum.
