SAE D-979 Heat Treatments
- Solution and precipitation heat treated
Solution heat treated: Heat to 1010 to 1038°C (1850 to 1900°F), hold at the selected temperature within ± 14°C (± 25°F) for a time commensurate with cross-sectional thickness, and quench as required;
Precipitation heat treated: Heat to 843 ± 8°C (1550 ± 15°F), hold at heat for 6 to 12 hours, cool at a rate equivalent to an air cool, heat to 704 ± 8°C (1300 ± 15°F), hold at heat for 16 ± 1 hours, and cool at the rate equivalent to an air cool.
