Product Description
409L Welded Pipe - 409 Stainless Steel Pipe
Stainless steel grade 409L is a general chromium, titanium stabilized, ferritic stainless steel primarily designed for automotive exhaust systems. With 11% chromium content—the minimum required for forming the passive surface film—this alloy offers excellent corrosion resistance combined with medium strength, good formability, and cost-effectiveness.
409L stainless steel provides superior corrosion resistance compared to carbon steel and serves as an economical alternative in moderately challenging environments where corrosion resistance and high-temperature oxidation properties are advantageous. This material is ideal for applications where mechanical performance and corrosion resistance take priority over aesthetic appearance.
Chemical Composition
Element C Mn Si P S Cr Ni Ti
