In order to ensure the yield strength of various types of stainless steel, mechanical properties of tensile strength, elongation and hardness to meet the requirements, you must go through stainless steel 430, solution treatment, aging heat treatment prior to delivery of steel. Corrosion resistance of stainless steel depends primarily on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and internal organizational structure, play a major role in the chromium. Chromium has a high chemical stability, steel coil stainless steel film formed on the surface of the metal with the outside world to isolate and protect steel from oxidation, increase the corrosion resistance of steel. After the destruction of the passive film, corrosion resistance decreased.
