Heat Treatment
Heat Treatment
- Annealing
- Temperature: 1010°C – 1120°C (1850°F – 2050°F)
- Process: Heat and rapidly cool. Relieves stresses, enhances ductility and toughness, and restores austenitic structure.
- Solution Annealing
-
- Temperature: 1038°C – 1149°C (1900°F – 2100°F)
- Process: Heat to dissolve carbides and precipitates, then rapidly cool. Improves corrosion resistance and ensures a uniform austenitic structure.
-
- Normalizing, Quenching, and Tempering: These processes are not used for 347 and 347H because these austenitic steels already possess a stable structure and do not require these treatments.
Characteristic
Characteristic
