Description
This alloy is one of the cold work, medium air hardening type tool steels. It contains chromium and molybdenum with a relatively high (1 %) carbon content and is capable of deep hardening from air quench so as to minimize distortion.

Applications
Used of die shapes, slitters, cutting, stamping, injection tools and similar applications where wear resistance is important

Continuous Cooling Transformation (CCT) Diagram

Time-Temperature Transformation (TTT) Diagram

Soft Annealing
Heat to 800-840^oC, 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 650^oC, 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 930-970^oC followed by air, oil, warm bath (500-550^oC) quenching. Hardness after quenching is 63 HRC.

Tempering
Tempering temperature: 150-550^oC

Forging
Hot forming temperature: 1050-850^oC.

Machinability
Machinability is medium, about 85 % that of the W group of tool steels which are rated at 100% for a baseline.

Corrosion Resistance
Corrosion resistance of this alloy is better than that of plain carbon steels. However it will rust unless given protective treatment.

Welding
This is an alloy steel and thus capable of being welded. Consult the alloy supplier for welding procedures.
