SAE MLX17 Heat Treatments

  • Solution heat treated by heating to 840°C ± 14 (1545°F ± 25), holding at heat for 120 minutes ± 15, and quenching in oil or water, cooling to -73°C (-100°F) or colder, holding at that temperature for not less than 8 hours, and warming in air to room temperature.
    Precipitation heat treating: H950 - temperature 510°C ± 6 (950°F ± 10), time 8 hours ± 0.3; H1000 - temperature: 538°C ± 6 (1000°F ± 10), time 8 hours ± 0.3.
  • Final heat treatment condition:
    H950: Solution heat treating at 840°C (1545°F); Oil, or water; Within 24 hours of removal from quenchant cool to -68°C (-90°F) or colder for 8 hours minimum, and air warm to ambient; Aging: 510°C (950°F) for 8 hours;
    H1000: Solution heat treating at 840°C (1545°F); Oil, or water; Within 24 hours of removal from quenchant cool to -68°C (-90°F) or colder for 8 hours minimum, and air warm to ambient; Aging: 538°C (1000°F) for 8 hours.
    When cooling from aging, an oil or water quench is preferred for section sizes greater than about 76.2 mm.

    Air refers to ambient air. When vacuum furnaces are used for heat treating, cooling in the backfilling gas is acceptable where cooling in still air or air cool is specified.
    If hardness exceeds the maximum specified, parts may be re-aged at the same or higher temperatures for a time not to exceed given values to obtain the required hardness.
    To produce a lower hardness for pretested material, a set temperature up to 6°C (10°F) higher than specified may be used.
    Soaking time for solution heat treatment is depending on thickness of the products.
    Tolerance for soaking time shall be +10, -0 minutes for 30 minute ages; +15, -0 minutes for 1 hour ages; +30 minutes, -0 minutes for longer ages.
    For sub-zero treatments, interruptions of the soaking period are permitted. The total soak time shall not include any time when the temperature is greater than -68°C (-90°F) due to interruptions.
