409 stainless steel, initially intended for automotive exhaust systems, is prized for its corrosion resistance. 409 and 409L stainless steel sheets offer affordability along with high corrosion resistance and weldability. With a lower chromium content, 409 stainless steel sheets mainly comprise iron, carbon, chromium, and titanium. The addition of titanium enhances corrosion resistance and weldability. On the other hand, 409L stainless steel sheets contain higher titanium and lower chromium content compared to 409, resulting in improved welding properties and corrosion resistance.

409 and 409L stainless steel coils are widely used materials in automotive exhaust systems, building decoration, furniture manufacturing, and other fields. They have good corrosion resistance, welding performance, and mechanical properties, suitable for use in high temperature and corrosive environments
