6.Heat Treatment
Annealing
Heating slowly and uniformly to 750~790℃, furnace cooling to
600℃ at a rate 10~20℃/hr, further cooling in air. Hardness after annealing: max. 205 HB. Suitable precautions must be taken to prevent excessive carburization or decarburization.
Stress relieving
600 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.
Hardening
AISI H10 steel is a very deep hardening steel, and although oil quenching may be used where maximum hardness is required, air hardening is recommended for most applications. The use of salt bath or controlled atmosphere furnace is desirable to minimize decarburization, and if not available, pack hardening spent pitch temperature employed is usually in the range of 982°C -1037°C.
1010 to 1050°C (1850 to 1922°F) Oil, salt bath (500-550°C / 932-1022°F), Holding time after temperature equalization: 15 to 30 minutes. Obtainable hardness: 52 -56 HRC
Tempering
Slow 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 hard-ness. The tempering chart shows average tem-pered hardness values. 3rd for stress relieving at a temperature 30 -50°C (86 to 122°F) below highest tempering temperature
7: Delivery condition
For hot forged or hot rolled bar, usually the delivery condition is hot forged or rolled, annealed, rough turned.
For hot forged plate, usually the delivery condition is hot forged, annealed, milled surface.
For hot rolled plate, usually the delivery condition is hot rolled, annealed, black surface.
