PROPRIETARY ASP 2078 Heat Treatments

  • Soft annealing in a protective atmosphere at 850-900°C for 3 hours, followed by slow cooling at 10°C/h down to 700°C, then air cooling.

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

    Hardening in a protective atmosphere with preheating in 2 steps at 450-500°C and 850-900°C and austenitising at a temperature suitable for chosen working hardness. Cooling down to 40-50°C.

    Tempering at 560°C three times for at least 1 hour each time. Cooling to room temperature < 25°C between temperings.
