3.Introduction :
DescriptionMedium alloy, oil-hardening tooling steel, which is hard-wearing.
ApplicationsMould, wood and paper processing tools, slitting blades, tobacco blades.
Soft AnnealingHeat to 720-750oC, cool slowlyin furnace to <550oC, then air. This will produce a maximum Brinell hardness of 225.Stress RelievingStress 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.HardeningHarden from a temperature of 790-820oC, 820-860oC followed by water or oil quenching. Hardness after quenching is 63-67, 63-66 HRC.TemperingTempering temperature: 150-300oC. Hardness after tempering is 56-65 HRC.4.We are the ISO 9001:2000 authentication enterprises and we can provide the enterprise's quality written guarantee for all the exported products.
