SAE QE22A Heat Treatments

  • Solution heat treatment
    Heated at 975-995°F (524-535°C). Incremental steps or a uniform heating rate shall be used to prevent eutectic melting which can irreversibly damage castings. A protective atmosphere containing sufficient sulfur dioxide, carbon dioxide, or satisfactory oxidation inhibitor shall be used when solution heat treating at or above 750°F (399°C). Recommended soaking time is 4-8 hours (soaking time starts when all temperature control sensing elements are within 10°F (6°C) of the set or offset temperature). Heavy section castings, t ≥ 25.4 mm, may require longer soaking time than indicated.
    Quenched in water (or other suitable media) held at 140-196°F (60-91°C). During the quench, the quenchant temperature shall not rise more than 25°F (14°C).
    Aging (precipitation heat treatment)
    Temper T6 - artificial aging from the solution heat treated (T4) temper. Heated for 8 hours at 400°F (204°C). Protective atmosphere is not required.
    Rework solution heat treatment
    Heated at 950°F (510°C). Recommended soaking time is 1-2 hours.
    Quenched in water (or other suitable media) held at 140-196°F (60-91°C).
  • At least one set of tensile specimens shall, during each stage of heat treatment, be placed into a batch-type furnace with each load of castings or into a continuous furnace at intervals of not longer than 3 hours; Tensile Specimens at 400 °F (204 °C): heated to 400 °F ± 5 °F (204 °C ± 3 °C), held at heat for 10 minutes ± 1 minute before testing, and tested at 400 °F ± 5 °F (204 °C ± 3 °C).
