PROPRIETARY ASP 2190 Heat Treatments

  • Soft annealing in a protective atmosphere at 920-950°C for 3h, followed by slow cooling at 10°C/h down to 700°C, then air cooling.

    Stress-relieving at 600-700°C for approximately 2h, 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 the given application and wanted hardness level (max 1150°C). Cooling down to 40-50°C.

    Tempering at 580°C two times for at least 1h each time. Cooling to room temperature < 25°C between tempering.

    It is important to respect the maximum hardening temperature at 1150°C as any higher hardening temperature will result in a rapid decrease in toughness.
