SAE AerMet 100 Heat Treatments

Bars and forgings: normalized by heating to 899 ± 14°C (1650 ± 25°F), holding at heat for 60 ± 15 minutes, and cooling in air to a temperature between 7 and 93°C (45 and 200°F), and overaged by heating to 677 ± 14°C (1250 ± 25°F), holding at heat for 16 hours minimum, and air cooled.
Response to heat treatment:
Austenitization: heated to 885 ± 14°C (1625 ± 25°F) and held at temperature for 60 minutes + 15/- 0 minutes and quenched using a suitable media to below 204°C (400°F) within 1 hour, and below 66°C (150°F) within 2 hours followed by air cooling or faster to room temperature.
Cold Stabilization: Within 8 hours of quenching as specified, the specimen shall be cooled to -73 ± 8°C (-100 ± 15°F) for a minimum of 1 hour. After cold stabilization, material shall be air warmed to room temperature.
Aging Treatment:
Aging at 482°C (900°F) - heated to 482 ± 6°C (900 ± 10°F) for 4 to 8 hours. Forgings with variable section thickness may be aged at 477 ± 6°C (890 ± 10°F) for 4 to 8 hours in order to avoid overaging thin sections.
Aging at 468°C (875°F) (Alternate when specified) - heated to 468 ± 6°C (875 ± 10°F) for 4 to 8 hours. Forgings with variable section thickness may be aged at 463 ± 6°C (865 ± 10°F) for 4 to 8 hours in order to avoid overaging thin sections.
Bars: Shall be annealed by heating to 1250 °F ± 25 (677 °C ± 14), holding at heat for not less than 16 hours, and cooling in air. Forgings: Shall be normalized by heating to 1650 °F ± 25 (899 °C ± 14), holding at heat for 60 minutes ± 15, cooling in air to room temperature, and annealed by heating to 1250 °F ± 25 (677 °C ± 14), holding at heat for not less than eight hours, and forced-air cooling. Heat treated: heating to 1625 °F ± 25 (885 °C ± 14), holding at heat for 60 to 75 minutes, and cooling at a rate equivalent to an air cool to ambient temperature, cooling to -100 °F ± 15 (-73 °C ± 8), holding at temperature for 60 minutes ± 5, warming at a rate equivalent to an air warm to room temperature, and aged by heating to 875 °F ± 10 (469 °C ± 6) , holding at heat for five to eight hours, and cooling at a rate equivalent to an air cool.
