Product Description
409 441 439 430 409L 436L Stainless Steel Welded Tubes for Exhaust Systems
Stainless steel grade 409L is a 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.
Material Overview
409L stainless steel provides superior corrosion resistance compared to carbon steel, making it ideal for mildly challenging environments where mechanical properties and corrosion resistance take priority over appearance. This material excels in high-temperature oxidation resistance applications.
