PROPRIETARY M-2 Heat Treatments


  • Annealing at 840 - 880°C, hold for at least 2h, furnace cooling by 10°C/h to 700°C, cooling in air. Stress relieving at 600 - 680°C, hold for at least 2h, cooling slowly to 500 °C and then in air. Hardening: Initial slow preheating to 500 - 550°C, second preheating to 850 - 880°C,heat to hardening temperature in the range 1200 - 1220°C and hold at temperature, cooling in oil or salt bath at 530 - 580°C. Tempering at 530 - 580°C.
