Product Description

409 Stainless Steel Sheet 1.4509 EN10088-2-2014 409L SS Sheet

409 stainless steel is a cost-effective ferritic grade widely recognized as the "muffler grade" due to its dominant application in automotive exhaust systems.

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

409 stainless steel withstands aggressive automotive conditions including high temperatures at manifold connections, sulphuric acid condensate, and de-icing salt exposure. Despite these severe conditions, this 11% chromium grade has proven reliable for decades in exhaust applications.

Exhaust components require extensive forming operations including bending, expanding, and pressing into complex shapes. The ferritic structure of 409 stainless steel provides remarkable formability to meet these demanding manufacturing requirements.
