MIL HY-80 Heat Treatments
- The bars shall be quenched and tempered. May be water quenched after tempering. Rapid cooling shall be employed following stress relief. Minimum tempering temperature 649°C and minimum stress relief temperature 593°C.
- The forgings shall be quenched and tempered. When necessary, double tempering is permitted and the restrictions for single tempering shall apply to double tempering. The final tempering temperature shall be not less than 635°C (1175°F). After tempering the forgings shall be removed from the furnace and rapidly cooled by water quenching or forced air. The stress relief temperature shall be 607 ± 14°C (1125 ± 25°F). If the forgings are stress relived after final tempering If the forgings are stress relieved after final tempering, the stress relief temperature shall not exceed the tempering temperature and shall be not less than 1100°F (593°C).
