Chemical Composition (in weight %)

CSiMnCrMoNiVWOthers
1.020.200.23---0.10--


Applications
Cold working tools for steels and metals when hard surface and tough core are demanded – tap drills, dies, broaching tools, stone working tools.


Physical properties (average values) at ambient temperature

Modulus of elasticity [103 x N/mm2]: 210
Density [g/cm3]: 7.85
Thermal conductivity [W/m.K]: 45.0
Electric resistivity [Ohm mm2/m]: 0.20
Specific heat capacity[J/g.K]: 0.46

11.112.112.913.513.9


Soft Annealing
Heat to 680-720oC, cool slowly. This will produce a maximum Brinell hardness of 213.


Stress Relieving

Stress relieving to remove machining stresses should be carried out by heating to approx. 600-650oC, 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 760-800oC followed by water quenching. Hardness after quenching is 65 HRC.
