This will produce a maximum Brinell hardness of 240. Stress Relieving: Stress relieving to remove machining stresses should be carried out by heating to 650°C, holding for one hour at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment. Hardening: Harden from a temperature of 1080-1160°C followed by air, oil or warm bath quenching. Hardness after quenching is 47-53 HRC. Tempering Tempering temperature: See the table bellow. Tempering Temperature (oC) vs. Hardness (HRC) 400°C 500°C 550°C 600°C 650°C 700°C 49 49 51 50 46 36 Charateristics: a.
