Heat Treatment

Annealing
650 to 700°C
Slow controlled cooling in furnace at a rate of 10 to 20°C/hr (50 to 68°F/hr) down to approx. 600°C, (1112°F) further cooling in air.
Hardness after annealing: max. 248 HB.

Stress relieving
Approx. 650°C
Slow cooling in furnace; intended to relieve stresses set up by extensive machining, or in complex shapes. After through heating, hold in neutral atmosphere for 1 - 2 hours.

Tempering
Slow heating to tempering temperature im- mediately after hardening / time in furnace 1 hour for each 20 mm of workpiece thickness but at least 2 hours / cooling in air. It is recommended to temper at least twice.
A third tempering cycle for the purpose of stress relieving may be advantageous.

Hardening
830 to 870°C / oil
870 to 900°C / air
Holding time after temperature equalization: 15 to 30 minutes.
Obtainable hardness:52 - 58 HRC in oil, 44 - 50 HRC in air.
