The corrosion resistance of stainless steel depends on the alloying elements contained in the steel. Chromium is the basic element to make stainless steel corrosion resistance, when the chromium content in steel reaches about 12%, chromium and the role of oxygen in the corrosive medium, the formation of a very thin oxide film on the surface of the steel (since the passivation film), can prevent further corrosion of the steel substrate.
In practice, the steel that is resistant to corrosion by weakly corrosive media is often called stainless steel, while the steel that is resistant to corrosion by chemical media is called acid-resistant steel.
