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
