Heat Treatment
Heat Treatment
- Solution Annealing: Applicable to 303Se Plate, Sheet, Tube, Round Bar. Heat 303Se stainless steel to 1010°C to 1120°C, then cool rapidly (usually water quenching or air cooling).
- Stress Relieving Annealing: Applicable to 303Se Plate, Sheet, Tube, Round Bar. Usually carried out at a lower temperature (about 300°C to 400°C), the main purpose is to remove the residual internal stress after cold working or welding.
- Annealing: Applicable to 303Se Plate, Sheet, Tube, Round Bar. Heat the material to 800°C to 900°C, then cool slowly.
- Hydrogen Relief Annealing: Applicable to 303Se Plate, Sheet, Tube, Round Bar. Annealing is performed at a lower temperature (such as 200°C to 400°C) to remove hydrogen embrittlement caused by electroplating, pickling or welding.
- Precipitation Hardening, Nitriding, Quenching and Tempering are not applicable to 303Se stainless steel.
