Model Number: ZXL087 Brand Name: Baosteel, TISCO Key Specifications/Special Features: DescriptionTungsten-chromium hot work steel suitable for water coolingApplicationsWater cooled dummy blocks for the extrusion of copper and copper alloys, hand casting chills for copper alloysPhysical properties (average values) at ambient temperatureModulus of elasticity [10³x N/mm²]: 210
Density [g/cm³]: 7.80
Chemical composition (in weight%)
C 0.30
Si 0.95
Mn 0.40
Cr 1.05
V 0.18
W 3.75
Soft annealing
Heat to 820 to 840°C, cool slowly in furnace
Holding time 4-6 hours
This will produce maximum Brinell hardness of 230
Stress relieving
Stress relieving to remove machining stresses should be carried out by heating to 650°, holding for one hour at heat, followed by slow cooling
Time is 1-2 hours
This operation is performed to reduce distortion during heat treatment
Hardening
Harden from temperature of 960 to 1050°C followed by water or oil quenching Hardness after quenching is appr 52 HRC (water quenching), 47 HRC (oil quenching)
Tempering
Tempering temperature: 560 to 700°C
Nit riding
Possible
Preheating before use: 200 to 300°C, absolutely necessary
Forging
Hot forming temperature: 1100 to 850°C
