Designation by Standards
Chemical Composition (in weight %)
Low alloyed carbon tool steel with good hardenability.
Forging hammers and tools, punchers for paper and skin, agricultural tools, tools for soft and medium hard rocks.
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 680-720oC, cool slowly in furnace.
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.
Harden from a temperature of 790-820oC followed by water quenching. Hardness after quenching is 63 HRC.
Tempering temperature: See the data bellow.
Tempering Temperature (oC) vs. Hardness (HRC)
Hot forming temperature: 1050-800oC.
