PROPRIETARY ASP 2048 Heat Treatments
- Soft annealing in a protective atmosphere at 850-900°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 chosen working hardness. Cooling down to 40-50°C.
Tempering at 560°C three times for at least 1h each time. Cooling to room temperature < 25°C between temperings.
