Permanent Mold Castings:
Solution Heat Treated (1) at 527(2) ± 6°C (980(2) ± 10°F), 14-20 hours; Precipitation Heat Treated: at 154(3) ± 6°C (310(3) ± 10°F), 20 hours.
Temper T7
Sand Castings:
Solution Heat Treated (1) at 527(2) ± 6°C (980(2) ± 10°F), 14-20 hours; Precipitation Heat Treated: at 188(3) ± 6°C (370(3) ± 10°F), 5 hours.
Permanent Mold Castings:
Solution Heat Treated (1) at 527(2) ± 6°C (980(2) ± 10°F), 14-20 hours; Precipitation Heat Treated: at 188(3) ± 6°C (370(3) ± 10°F), 5 hours.
(1) Quench in water at 65 to100°C (150 to 212°F) except as noted.
(2) Step solution heat treat 2h at 510°C (950°F) prior to 527°C (980°F) temperature to avoid eutectic meeting.
(3) Hold at room temperature for 12–24h between solution and precipitation heat treatments. - Annealing at 427°C (800°F), minimum soak time is 1 hour; Air cooling;
Solution heat treatment shall be at the temperature: 527°C (980°F), minimum soak time is 14 hours and Quenched;
A step solution treatment at 513°C (955°F), for not less than 2 hours prior to the noted solution treatment, is recommended.
Temper after Solution treatment shall be T4 and delay at room temperature.
Aging (precipitation heat treatment):
Condition before Aging W or T4;
Aging at 188°C (370°F), soak time is 5 minimum hours;
Temper T7 after Aging.
