  • Mat.No. 1.2063/DIN 145Cr6

Designation by Standards

Mat. No.DINENAISI
1.2063145Cr6--


Chemical Composition (in weight %)

CSiMnCrMoNiVWOthers
1.500.230.601.40-----


Applications

Small to medium size blanking and punching dies, shear blades, thread cutting tools, reamers, gauges and similar measuring instruments.


Physical properties (avarage values) at ambient temperature

Modulus of elasticity [103 x N/mm2]: 210
Density [g/cm3]: 7.80


Soft Annealing

Heat to 740-760oC, 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 approx. 650oC, 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 830-860oC followed by oil quenching (interrupt at approx. 150oC). Hardness after quenching is 64 HRC.
