DIN X30WCrV93 hot work tool steel plate

Model Number: ZXL076 Brand Name: Baosteel, TISCO Key Specifications/Special Features: Description:This alloy is one of the hot work, tungsten containing tool steelsTungsten content is beneficial for hot strength at red heat, although toughness is somewhat reducedApplications:Used for hot working dies and tooling such as die casting, extrusion and hot forming of partsPressure die casting tools, moulds for Cu and Cu-alloysThis grade is not used for water cooled toolsSoft annealing:
Heat to 780-810℃, cool slowly
This will produce a maximum Brinell hardness of 240
Stress relieving:
Stress relieving to remove machining stresses should be carried out by heating to 650℃, holding for one hour at heat, followed by air cooling
This operation is performed to reduce distortion during heat treatment
Hardening
Harden from a temperature of 1080-1160℃followed by air, oil or warm bath quenching. Hardness after quenching is 47-53 HRC.
Tempering Temperature (℃) vs. Hardness (HRC)
Forging
Hot forming temperature: 1150-926℃.
Machinability
The tungsten content makes H21 somewhat difficult to machine. As compared to the W group of water hardening low alloy steels rated at 100% for machinability the H21 would rate 55%.
Corrosion Resistance
This is a steel alloy and does not have corrosion resistance. It will rust unless given protective treatment.
Welding
This alloy may be welded.
