Why stainless steel flange corrosion resistance By yaang.com

Why corrosion resistant stainless steel flange? All metal flange and atmospheric oxygen reaction, a layer of oxide film on the surface. Unfortunately, in the ordinary carbon steel on the oxidation of formation of iron oxide to continue to make a thorough, kept expanding rust, eventually forming holes. Can use paint or resistant to oxidation of the metal (for example, zinc, chromium and nickel) to ensure that the surface of the carbon steel metal plating, however, as most people know, the protection is only a thin film on the stainless steel flange. If the protective layer is severely damaged, the following flange began to rust.
