Designation by Standards
Chemical Composition (in weight %)
Low alloyed Cr-V cold working tool steel.
Circular saws for timber, saws for non ferous, machine saws, measuring tools, tools for wood working (axes, knivesp, punches, guide rods, twist drills, reamers, ejector pins, dentist’s drills.
Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 210
Density [g/cm3]: 7.80
Thermal conductivity [W/m.K]: 33.5
Heat to 710-850oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 220.
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 810-840oC, 780-810oC followed by oil (up to diamter 15 mm) or water (for diameter higher then 15 mm) quenching Hardness after quenching is 64 HRC.
Tempering temperature: See the data bellow.
Tempering Temperature (oC) vs. Hardness (HRC)
Hot forming temperature: 1050-850oC.
This is an alloy steel and it is not corrosion resistant. It will rust unless protected.
