| Weight (%) | 0.03 max | 2.0 max | 0.02 max | 1.0 max | 0.03 max |
Optimal forging temperature: 1100-1250°C. Reheat as necessary and cool in still air.
Material in annealed condition is readily machinable using all conventional methods.
Compatible with standard electric arc welding processes. Oxyacetylene welding not recommended due to potential carbon pickup.
Annealing: Heat to 1020-1120°C with sufficient soak time, followed by water quenching.
- 50:50 austenite-ferrite microstructure for optimal strength and ductility
- Yield strength exceeding 450 MPa (65 KSI) in annealed condition
- High resistance to pitting, stress, and crevice corrosion
- Excellent performance in chloride and hydrogen sulfide environments
- Superior alternative to 300 series austenitic stainless steels
- Sheet and Plate
- Round Bar and Flat Bar
- Pipe & Tube (welded and seamless)
