Stock 100CrMn6/1.3520 Chromium-manganese alloy bearing steel
ApplicationsRoller bearings with thickness up to 50 mm.Â
DescriptionMedium alloy, oil-hardening tooling steel, which is hard-wearing.
Quality Standard:DIN 17230-1980 Ball and Roller Bearing Steels
Chemical Composition(%)| 0.90-1.05 | 0.50-0.70 | 1.00-1.20 | 0.030 max | 0.025 max | 1.40-1.65 | 0.30 max | 0.30 max |
Soft AnnealingHeat to 760-800oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 217.
NormalizingNormalizing temperature: 860-900oC.
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 830-890oC followed by oil quenching. Hardness after quenching is approx. 64 HRC.
TemperingTempering temperature: 150-180oC.
ForgingHot forming temperature: 1100-850oC.Â
