Hot Forming:
Forging: 1100 to 850ºC, slowing cooling in furnace.
Heat Treatment:
Annealing: 650 to 700ºC, slow cooling in furnace (10-20ºC/hr), down to 600ºC, cooling in air. Hardness after annealing: max. 250 HB.
Stress relieving: approx. 650ºC, slow cooling in furnace. Hold in neutral atmosphere for 1 to 2hours.
Hardening: 830 to 870ºC, oil/870 to 900ºC, air, hold 15 to 30 minutes. Hardness , 52 to 58HRC in oil, 44 to 50 HRC in air.
Tempering: 300 to 600ºC. Slowly heating to tempering temperature right after hardening. Recommended to temper at least twice.
