PROPRIETARY ASP 420V Heat Treatments

  • Soft annealing in a protective atmosphere at 930-970°C for 3 hours, followed by slow cooling at 10°C/h down to 750°C, then air cooling.

    Stress-relieving at 600-700°C for approximately 2 hours, slow cooling down to 500°C.

    Harden at 1075°C to 1175°C for chosen hardness.

    Temper for best corrosion resistance at 200-400°C (260°C recommended) 2 times for 2 hours each (minimum). Deep cooling after first tempering is possible and highly recommended for low temperature tempering to ensure thermal stability. Temper at 530-550°C can be used for best dimension stability and stress relieving.
