Typical applications are for structural use, such as aircraft landing gear, power transmission gears and shafts and other structural parts, general engineering parts, hrough-hardened gears, connecting rods and bolts, gun barrels.
Normalizing temperature: 850-880oC.
Stress relieving to remove machining stresses should be carried out by heating to approx. 650oC, holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.
Harden from a temperature of 830-860oC followed by oil quenching. Qenching temperature in the end-quench test is 850oC.
Tempering temperature: 540-660oC.
8.EN24 material :the tempering temperature can be "tempered to the desired hardness".
