Model Number: ZXL047 Brand Name: Baosteel, TISCO Key Specifications/Special Features: DescriptionLow alloyed cold working tool steelApplicationsCutting tools for steels and metals, broaching tools, thread cutting tools, files, chisels, drawing dies, cutting tools for the hardest stoneChemical composition (in weight%)C 1.38
Si 0.20
Mn 0.23
Physical properties (averagevalues) at ambient temperature
Modulus of elasticity [10³xN/mm²]: 210
Density [g/cm³]: 7.85
Soft annealing
Heat to 680-720℃, cool slowly
This will produce a maximum Brinell hardness of 210
Stress relieving
Stress relieving to remove machining stresses should be carried out by heating to approx. 600 to 650℃, holding for 1-2 hoursat heat, followed by air cooling
This operation is performed to reduce distortion during heat treatment
Hardening
Harden from temperature of 760 to 780℃ followed by oil or water quenchingwith addition of NaCl Hardness after quenching is approx 65 HRC
Forging
Hot forming temperature: 1000 to 800℃
