Heat Treatment
Heat Treatment
- Normalizing
- Generally not applicable to 321 stainless steel
- Annealing
- Heat to 815°C to 900°C (1500°F to 1650°F) and hold at the temperature. Cool slowly in the furnace or the air.
- Softens the material, improves ductility, and relieves internal
- Solution Annealing
- Heat to 1010°C to 1120°C (1850°F to 2050°F) and hold at the temperature. Then, rapidly cool by water quenching.
- Restores corrosion resistance and flexibility.
- Quenching
- After solution annealing, rapidly cool by water quenching
- Maintains corrosion resistance, and prevents carbide precipitation.
- Tempering
- Generally not applicable to 321 stainless steel
- Stress Relieving
- Heat to 205°C to 425°C (400°F to 800°F) and hold. Cool slowly in the air.
- Reduces residual stresses and improves dimensional stability.
