Heat Treatment
Hardening: 1150 to 1230°C (2102 to 2246°F) Oil, salt bath (500- 550°C (932 - 1022°F), air, gas.
Tempering: Slow heating to tempering temperature immediately after hardening/time in furnace: 1 hour for every 20 mm of workpiece thickness, but not less than 2 hours/ air cooling (minimum holding time: 1 hour). 1st tempering and 2nd tempering to desired working hardness. Average obtainable hardness values are shown in the tempering chart. 3rd tempering for stress relieving, 30 - 50°C (86-122°F) below highest tempering temperature.
