Heat Treatment
Heat Treatment
- Annealing
- Temperature: 1010°C – 1120°C (1850°F – 2050°F)
- Process: Heated and rapidly cooled in air or water, relieving internal stresses, improving ductility and toughness, restoring uniform austenitic grain structure.
- Solution Annealing
- Temperature: 1038°C – 1149°C (1900°F – 2100°F)
- Process: Heated to dissolve carbides and rapidly cooled, preventing chromium carbide formation, maintaining a homogenous austenitic structure.
- Stress Relieving
- Temperature: 200°C – 400°C (392°F – 752°F)
- Process: Heated to relieve residual stresses without altering microstructure, improving stability and reducing stress corrosion cracking risk.
- Stabilization Heat Treatment
- Temperature: 870°C – 900°C (1600°F – 1650°F)
- Process: Heated to precipitate stabilizing carbides, preventing sensitization, enhancing resistance to intergranular corrosion in high-temperature environments.
- Normalizing, Quenching, and Tempering: Not applicable to 347 Stainless Steel due to its austenitic nature, which does not benefit from these treatments used for carbon and martensitic steels.
Characteristic
Characteristic
