Shanghai Bozhong Metal Group Co. Ltd

Model Number: ZXL027 Brand Name: Baosteel, TISCO Key Specifications/Special Features: DescriptionLow alloyed W cold working tool steelApplicationTwist drills and tapes, ejectors, punches, reamers, countersinks, engraving tools, metal cutting saws usually delivered as silver steelChemical composition (in weight%)C: 1.20Si: 0.23Mn: 0.28Cr: 1.20V: 0.10W: 1.00Physical properties (averagevalues) at ambient temperatureModulus of elasticity [103xN/mm2]: approx 215Density [g/cm3]: 7.85Thermal conductivity [W/m. K]: 31.5Electric resistivity [ohm mm2/m]: 0.30Specific heat capacity [J/g. K]: 0.46Soft annealingHeat to 720 to 750℃, 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 approx 650℃, holding for 1-2 hours at heat, followed by air cooling
This operation is performed to reduce distortion during heat treatment
Hardening
Harden froma temperature of 760 to 820℃, 800 to 840℃ followed by water or oil quenching
Hardness after quenching is min. 64-66 HRC
Tempering
Tempering temperature: 150 to 250℃
Forging
Hot forming temperature: 1050 to 850℃
