409L stainless steel Strips introduction

409L stainless steel is a low carbon ferritic stainless steel, containing 11% chromium and a small amount of titanium, with excellent corrosion resistance and oxidation resistance, especially in high temperature environments. Its low carbon design improves welding performance and reduces carbide precipitation in the welding area, thereby increasing resistance to intergranular corrosion.
