Product Application
The 409L/S40903 stainless steel is primarily used for manufacturing automotive exhaust gas treatment devices.
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
- Unique crystallization behavior prevents columnar crystal formation
- Minimal δ phase content due to low carbon content
- Coarse ferrite structure development requires careful processing control
