Shanghai Bozhong Metal Group Co. Ltd

Model Number: ZXL057 Brand Name: Baosteel, TISCO Key Specifications/Special Features: Descriptions:Medium alloy cold work steel, oil hardening, performances slightly inferior to those of our grade meriloex, moderate deep hardening properties, good toughnessApplications:Small to medium size blanking and punching dies, shear blades, thread cutting tools, reamers, gauges and similar measuring instrumentsChemical composition (in weight%):C 1.50
Si 0.23
Mn 0.60
Cr 1.40
Physical properties (average values) at ambient temperature:
Modulus of elasticity [10³xN/mm²]: 210
Density [g/cm³]: 7.80
Soft annealing:
Heat to 740 to 760°C, cool slowly in furnace, this will produce a maximum brinell hardness of 230
Stress relieving:
Stress relieving to remove machining stresses should be carried out by heating to approximately 650°C, holding for 1-2 hours at heat, followed by air cooling, this operation is performed to reduce distortion during heat treatment
Hardening:
Harden from temperature of 830 to 860°Cfollowed by oil quenching (interrupt at approximately 150°C) Hardness after quenching is 64 HRC
Forging:
Hot forming temperature: 1050 to 850°C
