Stress relieving600 to 650°C (1112 to 1202°F)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. Hardening1000 to 1040°C (1832 to 1904°F)Oil, salt bath (500 - 550°C / 932-1022°F), airHolding time after temperature equalization: 15 to 30 minutes.Obtainable hardness:52 - 56 HRC in oil or salt bath,50 - 54 HRC in air. TemperingSlow heating to tempering temperature immediately after hardening / time in furnace 1 hour for each 20 mm of work piece 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.1st tempering approx. 30°C (86°F) above maximum secondary hardness.2nd tempering to desired working hardness.The tempering chart shows average tempered hardness values.3rd for stress relieving at a temperature 30 - 50°C (86 to 122°F) be low highest tempering temperature.
