Stainless steel grade 409L is a general chromium, titanium stabilized, ferritic stainless steel specifically designed for automotive exhaust systems. With 11% chromium content - the minimum required for forming the passive surface film that provides corrosion resistance - this alloy combines excellent elevated temperature corrosion resistance with medium strength, good formability, and cost-effectiveness.
Key Features
Superior corrosion resistance compared to carbon steel
Excellent high-temperature oxidation resistance
Good mechanical properties and formability
Cost-effective alternative for challenging environments
Ideal for applications where mechanical properties and corrosion resistance take priority over appearance
