PROPRIETARY 17-7 PH Heat Treatments

  • 3 essential steps are required: austenite conditioning, cooling to transform the austenite to martensite and precipitation hardening.
    Condition A: Mill Annealed 1066°C ± 14°C (1950°F ± 25°F);
    Austenite Conditioning: 1. Heat to 760°C ± 14°C (1400°F ± 25°F), hold for 90 minutes; or 2. Heat to 954°C ± 8°C (1750°F ± 15°F), hold for 10 minutes, air cool to room temperature - results in Condition A 1750;
    Transformation: 1. Within 1 hour, cool to 16 +0/-5.5 °C (60 +0/-10 °F), hold for 30 minutes - results in Condition T; or 2. Within 1 hour, start cooling to -73°C ± 5.5°C (-100°F ± 10°F), hold for 8 hours, air warm to room temperature - results in Condition R 100;
    Precipitation Hardening: 1. Heat to 566°C ± 5.5°C (1050°F ± 10°F), hold for 90 minutes, air cool to room temperature - results in Condition TH 1050; or 2. Heat to 510°C ± 5.5°C (950°F ± 10°F), hold for 60 minutes, air cool to room temperature - results in Condition RH 950.
    Condition CH 900: Condition A material is transformed to martensite at the mill by cold reduction to Condition C. Percipitation hardening - heat to 482 ± 5.5°C (900 ± 10°F), hold for 60 minutes, air cool to room temperature.
  • Annealed at 1038 - 1121°C (1900 - 2050°F)
    Spring + Aged (CH 900): Heated at 482°C (900°F) for 60 min, air cooled
