Designation by Standards
Chemical Composition (in weight %)
This alloy is on of the cold work, oil hardening type tool steels.
Planing machine blades, tap drills, machine blades for cutting paper, paperboard and tobacco.
Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: Approx. 210
Density [g/cm3]: 7.80
Coefficient of Linear Thermal Expansion 10-6 oC-1
Heat to 720-750oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 230.
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.
Harden from a temperature of 780-820oC, 800-860oC followed by water or oil quenching. Hardness after quenching is min. 64-65 HRC.
Tempering temperature: 150-300oC.

Hot forming temperature: 1050-850oC.
Corrosion resistance of this alloy is better than that of plain carbon steels. However it will rust unless given protective treatment.
