In order to ensure the yield strength of various types of stainless steel coil, the mechanical properties of tensile strength, elongation and hardness to stainless steel sheet the requirements, you must go through annealing, solution treatment, aging heat treatment prior to delivery of stainless steel coil. The corrosion resistance of stainless steel coil depends primarily on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and the internal organizational structure of stainless steel coils, played a major role in chromium. Chromium has a high chemical stability, steel magnetic stainless steel film formed on the surface of the metal with the outside world to isolate and protect steel from oxidation, increasing corrosion resistance of steel. After the destruction of the passive film, corrosion resistance decreased.
