SAE 5876 Heat Treatments

  • Solution Heat Treatment: Strip shall be solution heat treated by heating to 1177°C ± 14°C (2150°F ± 25°F), holding at heat for a time commensurate with section thickness, and cooling as required.
    Aging Heat Treatment: Aged by heating to a temperature within the range 454 to 510°C (850 to 950°F), holding at the selected temperature within ±14°C (±25°F) for 5 to 51⁄2 hours, and cooling to room temperature at a rate equivalent to air cooling.
