Heat Treatment

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°C to 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 austenitizing 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.

Surface Treatment

The steel grade is a perfect substrate material for PVD coating. If nitriding is requested, a small diffusion zone is recommended but avoid compound and oxidized layers.

Guidelines For Hardening

Tempering temperature in °C

Hardness after hardening, quenching and tempering 3 x 1 hour
