Mat.No. 1.2885, DIN X32CrMoCoV3-3-3, AISI H10A

Designation by Standards

Chemical Composition (in weight %)

Description
This alloy is on of the hot work, cobalt containing tool steel.

Applications
Hot pressing tools exposed to severe stresses in contact with the die insert – mandrels, stamps, punching tools, dies, etc. 

Physical properties (avarage values) at ambient temperature
Modulus of elasticity [10³ x N/mm²]: 210
Density [g/cm³]: 7.88

Coefficient of Linear Thermal Expansion 10^-6 oC^-1

Soft Annealing
Heat to 800-840^oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 250.

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 1020-1060^oC followed by oil, air or warm bath quenching. Hardness after quenching is 49-53 HRC.

Tempering
Tempering temperature: See the table and diagram bellow.
