SAE AM-350 Heat Treatments

  • Solution heat treated by heating to 1010 to 1079°C (1850 to 1975°F), holding at the selected temperature within ±14°C (±25°F) for a time commensurate with cross-sectional wall thickness, and cooling as rapidly as possible to room temperature.
    1. Austenite condition:
    Tempered at 932 ± 14°C (1710 ± 25°F); 45min; wt= 25 mm
    2. Cool as rapidly as possible to room temperature
    3. Subzero treatment:
    Tempered at -73°C (-100°F) or lower; 1h (wt ≤ 0.25 mm) or 3h (wt > 0.25 mm)
    4. Warm in air to room temperature
    5. Temper:
    Tempered at 454 ± 14°C (850 ± 25°F); 3h cooling at a rate equivalent to air or faster
  • Annealed: heating to 1,950° ±25° F and holding at temperature for 45 minutes per inch of thickness, followed by water quenching. Heat treated: Austenite conditioned by heating to 1,710° ±25° F, held at heat for not less than 45 minutes per inch of thickness, quenched in water or otherwise quenched very rapidly to room temperature, cooled to -100° F or lower, held at this temperature for not less than 3 hours, warmed to room temperature, heated to either 1,000° F or 850° ±10° F, held at temperature for not less than 3 hours nor more than 4 hours, and air cooled to room temperature.
