Low alloy tool steel plate, material number 1.2542

Model Number: ZXL030 Brand Name: Baosteel, TISCO Key Specifications/Special Features: Description:This steel is one of the high duty shock resisting tool steel typesApplicationsAll kinds of cold and hot pneumatic tools, cold and hot cutting shears for plate, pressing diesChemical composition (in weight%)C: 0.50Si: 0.85Mn: 0.30Cr: 1.05V: 0.15W: 1.45Physical properties (averagevalues) at ambient temperature
Modulus of elasticity [103xN/mm2]: 210
Density [g/cm3]: 7.90
Thermal conductivity [W/m. K]: 25.0
Electric resistivity [ohm mm2/m]: 0.30
Specific heat capacity [J/g. K]: 0.46
Soft annealing
Heat 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 890 to 930℃, followed by oil or water quenching
Hardness after quenching is 56-59, 61-64 HRC
Tempering temperature: 150 to 400℃
Forging hot forming temperature: heat slowly and uniformly to 1000℃
Forge within a range of 1000/800℃ reheating if necessary
Cool slowly (preferably in a furnace) to avoid setting up stresses
Corrosion resistance of this alloy is better than that of plain carbon steels
However it will rust unless given protective treatment
