SAE 2124 Heat Treatments

  • Solution heat treating at 493°C for all forms.
    Aging treatment is mandatory. For plates: Starting temper is T351, final temper is T851 (sometimes used to designate final tempers), aging at 191°C for 12-13h.
    Full anneal: At 399-427°C, soaking time is minimum 1h (soak times listed are for up to 13 mm maximum thickness. Add 0.5 hour for each additional 13 mm of product or nested stack thickness or fraction thereof over 13 mm), cooling in furnace (furnace cool at 28°C degrees per hour maximum, to 260°C, air cool to room temperature or furnace cool at 28°C degrees per hour maximum, to 232°C, hold at 232°C for 6 hours, furnace or air cool to room temperature). Stress relief: At 333-349°C, soaking time is minimum 0.5h (soak times listed are for up to 13 mm maximum thickness. Add 0.5 hour for each additional 13 mm of product or nested stack thickness or fraction thereof over 13 mm), cooling in air.
  • Annealing: Soak for 2 to 3 hours at 404°C (760°F); cool at rate of 28°C (50°F) per hour or slower to 260°C (500°F ); further cooling rate optional.
    Solution heat treating temperature (for plate): 488-499°C (910- 930°F) , followed by an air cool and quenched.
