Shanghai Bozhong Metal Group Co. Ltd

Model Number: ZXL041 Brand Name: Baosteel, TISCO Key Specifications/Special Features: DescriptionMedium alloy, oil-hardening tooling steel, which is hard-wearingApplicationsRoller bearings with thickness up to 50mmChemical composition (in weight%)C: 0.97
Si: 0.60
Mn: 1.10
Cr: 1.53
Physical properties (averagevalues) at ambient temperature
Modulus of elasticity [10³xN/mm²]: 210
Density [g/cm³]: 7.85
Soft annealing
Heat to 760-800℃, cool slowly in furnace
This will produce a maximum Brinell hardness of 217
Normalizing
Normalizing temperature: 860-900℃
Stress relieving
Stress relieving to remove machining stresses should be carried out by heating to approx. 650℃, holding for 1hours at heat, followed by air cooling
This operation is performed to reduce distortion during heat treatment
Hardening
Harden froma temperature of 830-890℃, followed by oil quenching
Hardness after quenching is approx 64 HRC
Tempering
Tempering temperature: 150-180℃
Forging
Hot forming temperature: 1100-850℃
