ASTM A29 Standard Specification Steel Bars, Carbon and Alloy, Hot-Wrought, General Requirements

Heat treatment:

l FORGING:forming temperature: 1100-850℃

l SOFT ANNEALING: Heat to 730-760℃, cool slowly. This will produce a maximum Brinell hardness of 207.

l STRESS RELIEVING: Stress relieving to remove machining stresses should be carried out by heating to approx. 600-650℃, holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.

l HARDENING: Harden from a temperature of 780-810℃, 820-850℃ followed by water or oil quenching. Hardness after quenching is about 60 HRC.

l TEMPERING: Tempering temperature: 150-180℃.
