PROPRIETARY CRUCIBLE AIRDI 150 Heat Treatments

  • Annealed: Heat to 1600°F (870°C), hold 2 hours, slow cool 25°F (14°C) per hour to 1000°F (540°C) then air cool. OR heat to 1600°F (870°C), hold 2 hrs., cool to 1425°F (775°C) hold 6 hrs. then air cool. Stress relieved: Annealed Parts: Heat to 1200-1250°F (650-675°C), hold 2 hours, then cool in still air. Hardened Parts: Heat to 25-50°F (15-25°C) below the original tempering temperature, hold 2 hours, then cool in still air. Hardened: Preheat: Heat to 1100-1200°F (595-650°C), equalize, then to 1400-1450°F (760-790°C), equalize. Austenitize: 1825-1875°F (995-1025°C), Hold time at temperature 30-45 minutes. Quench: Air or positive pressure quench (2 bar minimum) to below 150°F (65°C). Temper: 400-1000°F (205-540°C). Temper 2 hours minimum each time or at least 1 hour per inch (25mm) of thickness. Double Temper. Cool to room temperature in between tempers.
