Characteristics
1. A kind of air hardening tool steel.
2. Good toughness with medium wear resistance and relatively easy to machine.
Heat Treatment
Annealing
800 to 850°C
Slow controlled cooling in furnace at a rate of 10 to 20°C/hr down to approx. 600°C, further cooling in air.
Hardness after annealing: max. 235 HB.
Hardening
950 to 980°C
Oil, salt bath (200 to 250°C or 500 to 550°C), air blast, still air. Tools of intricate shape or with sharp edges should preferably be hardened in air or salt bath. Holding time after temperature equalization:15 to 30 minutes. Obtainable hardness: 63 - 65 HRC
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 immediately after hardening/time in furnace 1 hour for each 20 mm of workpiece thickness, but at least 2 hours/cooling in air. For certain cases we recommend to reduce tempering temperature and increase holding time.
