Description
Low alloyed Cr-V cold working tool steel.
Applications
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
Soft Annealing
Heat to 710-850oC, cool slowly in furnace. This will produce a maximum Brinell
hardness of 220.
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 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
Tempering temperature: See the data bellow.
Increased carbon content heat resistant qualities
Greater tensile yield strength
Greater short and long term creep strength
Forged ratio: |
no less than 4:1
|
