Corrosion resistance of stainless steel

　　Asme B16.5 forged Butt Welding carbon steel flange

　　The corrosion resistance of the stainless steel plate mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, manganese, etc.) and internal organizational structure, is a chromium element plays the leading role. Chromium has the very high chemical stability, can be formed in the steel surface passivation membrane, metal and isolated, protect steel from oxidation, increase the corrosion resistance of steel sheet. After passivation membrane damage, corrosion resistance is decreased.
