Product Description

SUS409L Sheet 2b 2D Finished Suh409L 409L Stainless Steel Sheet

409L is a cost-effective ferritic stainless steel primarily used in automotive exhaust systems, earning it the common name "muffler grade."

Chemical Composition

Grade	C	Cr	Ni	Ti
409	0.03	10.5~11.7	0.50	8(C+N) min. 0.15~0.50

Key Characteristics

Basic corrosion and oxidation resistance
Optimized composition for superior formability
Weldable in thin sections (fully ferritic structure)
Cost-effective with stable pricing due to low alloy content

Automotive Applications

Automotive exhaust systems operate under extreme conditions including high temperatures at the manifold, sulfuric acid condensate, and de-icing salt exposure. Despite these harsh environments, the 11% chromium 409 grade has proven reliable for decades. The material's exceptional formability allows for bending, expanding, and pressing into complex shapes required for exhaust components.

Additional Applications

Heat exchangers, gas boilers, and fuel filters.
