Shanghai Bozhong Metal Group Co. Ltd

Model Number: ZXL025 Brand Name: Baosteel, TISCO Key Specifications/Special Features: DescriptionThis alloy is one of the cold work, oil hardening type tool steels, it is relatively inexpensive containing small amounts of manganeseTungsten and chromiumHardening by oil quench minimizes distortion and crackingApplicationsApplications include short run tooling for blanking dies, cold forming dies and cutting tools operating at ambient temperatureFor working tools, cutting blades, sizing and stamping toolsPhysical properties (average values) at ambient temperature
Density [g/cm³]: 8.0
Thermal conductivity [W/m.K]: 30.0
Chemical composition ( in weight%)
C: 1.43
Si: 0.23
Mn: 0.30
Cr: 0.35
V: 0.25
W: 3.05
Soft annealing
Heat to 720-750℃, cool slowly in furnace, this will produce a maximum Brinell hardness of 270
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 from a temperature of 800-830℃followed by water quenching, hardness after quenching is 66 HRC
Tempering
Tempering temperature: 100-250℃
Forging
Hot forming temperature: 1050-850℃
