Application & Description

The 409L/S40903 stainless steel is primarily used for manufacturing automotive exhaust gas treatment devices due to its excellent corrosion resistance and thermal stability.

Crystalline Characteristics

The solid and liquid two-phase region of 409L steel is very small, less than 30°C
There is almost no γ phase at high temperature, resulting in fine equiaxed crystal formation during crystallization
Unique crystallization behavior prevents columnar crystal formation, producing uniform equiaxed crystal structures
Minimal phase transitions from high to low temperature prevent grain coarsening and maintain structural integrity
