Model Number: ZXL034
Brand Name: Baosteel, TISCO
Key Specifications/Special Features:
DescriptionLow alloyed cold working tool steel.ApplicationsCold rolls, back-up rolls, straightening rolls, non-ferrous-2 and 4 high roll mills.Chemical Composition (in weight%)C: 0.87 Si: 0.30 Mn: 0.38 Cr: 1.75 V: 0.10 Mo: 0.28 Ni: 0.13 Physical properties (averagevalues) at ambient temperature Modulus of elasticity [103xN/mm2]: 210 Density [g/cm3]: 7.85 Thermal conductivity [W/m. K]: 35.0 Electric resistivity [Ohm mm2/m]: 0.30 Specific heat capacity [J/g. K]: 0.46 Soft annealing Heat to 720-750℃, 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 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 800-820℃, 830-850℃followed by oilor water quenching. Hardness after quenching is 64-67HRC. Tempering Tempering temperature: 200-600℃ Forging Hot forming temperature: 1150-850℃.
