 Corrosion-resistant stainless steel alloy depends on its composition (chromium, nickel, titanium, silicon, aluminum, etc.) and internal organizational structure, play a major role is chromium. Chromium has a high chemical stability, in the passive film formed on the surface of steel, the metal with the outside world to isolate and protect steel from oxidation and increase the corrosion resistance of steel. After the destruction of the passive film, corrosion resistance on the decline.
