Descripción de producto
ERW Welded Stainless Tube for Exhaust Systems
JIS G4312 Suh409L/1.4512/441/436L/439
Product Overview
409L welded pipe is a chromium, titanium-stabilized ferritic stainless steel specifically designed for automotive exhaust systems. With 11% chromium content, it forms a passive surface film that provides excellent corrosion resistance while offering medium strength, good formability, and cost-effectiveness.
Material Characteristics
Stainless steel grade 409L demonstrates superior corrosion resistance compared to carbon steel, making it ideal for mildly challenging environments where mechanical properties and corrosion resistance take priority over appearance. Its high resistance to corrosion and elevated temperature oxidation provides significant advantages in demanding applications.
