Description
Special cold work tool steel, air or oil hardenable with highest toughness.
Applications
Forging tools, dies of all sorts, shapes and sizes, hot forging and pressing tools for steel and metal. Moulds, bushings, piercers, etc.
Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 210
Density [g/cm3]: 7.86
Soft Annealing
Heat to 610-850oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 295.
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 880-910oC followed by air or oil quenching or warm bath quenching 180-220oC. Hardness after quenching is 56 HRC.
Tempering
Tempering temperature: See the data bellow.
