SAE AM-355 Heat Treatments

  • Solution Heat Treatment
    The product shall be solution heat treated by heating to 1038°C ± 14°C (1900°F ± 25°F), holding at the selected temperature for not less than 45 minutes per 25 mm of nominal thickness, and quenching in water or otherwise cooling as rapidly as possible to room temperature.
    As heat treated, sub-zero cooled, austenite conditioned, sub-zero cooled and tempered: Heat treated by heating at 1038°C ± 14°C (1900°F ± 25°F), held at heat for not less than 45 minutes per 25 mm of nominal thickness, and quenched in water. Cooled to -73°C (-100°F) or colder, held at this temperature for not less than three hours, and warmed in the air to room temperature. Austenite condition by heating to 954°C ± 6°C (1750°F ± 10°F), held at heat for 10 to 60 minutes, and quenched in water, cooled to -73°C (-100°F) or colder, held at this temperature for not less then three hours, and warmed in air to room temperature. Tempered by heating to 538°C ± 14°C (1000°F ± 25°F), held at heat for not less than three hours, and cooled in air
  • Bars and forgings shall be solution heat treated by heating to 1038°C ± 14°C (1900°F ± 25°F), holding at heat for 1 to 3 hours, and cooling as rapidly as possible to room temperature; cooling to -73°C (-100°F) or colder, holding at that temperature for not less than 3 hours, and warming in air to room temperature; austenite conditioned by heating to 954°C ± 14°C (1750°F ± 25°F), holding at heat for 10 to 60 minutes, and cooling as rapidly as possible to room temperature; cooling to -73°C (-100°F) or colder, holding at that temperature for not less than 3 hours, and warming in air to room temperature; and tempered by heating to 538°C ± 14°C (1000°F ± 25°F), holding at heat for not less than 3 hours, and cooling in air.
