Stainless steel Plate corrosion resistance

Stainless steel Plate corrosion resistance depends primarily on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and the internal organizational structure, play a major role are chromium. Chromium has a high chemical stability in the steel passive film formed on the surface, so that the metal with the outside world and separated from the protection of stainless steel plate will not be oxidized to increase the corrosion resistance of stainless steel plate capacity. After the destruction of the passive film, corrosion resistance on the decline.
