Product Description

Key Specifications/Special Features:
Description
This alloy is one of the common water hardening tool steel grades available
W1 is basically a simple high carbon steel and is easily hardened by heating and quenching in water, just as with plain carbon steel alloys
The W series of tool steels are a very simple alloy group, responsive to simple heating and water quenching for hardening
The alloy does undergo considerable distortion during quenching
Applications
W1 is commonly used for hand operated metal cutting tools, cold heading, embossing taps and reamers as well as cutlery
Chemical composition (in weight%)
C 1.05
Si 0.20
Mn 0.23
Physical properties (average values) at ambient temperature
Modulus of elasticity [103xN/mm2]: 210
Density [g/cm3]: 7.85
Thermal conductivity [W/m. K]: 45.0
Electric resistivity [ohms/mm2/m]: 0.20
Specific heat capacity [J/g. K]: 0.46
Soft annealing
Heat to 680 to 720°C, cool slowly in furnace
This will produce a maximum Brinell hardness of 213
Stress relieving
Stress relieving to remove machining stresses should be carried out by heating to approx 600-650°C, 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 760-800°C followed by water quenching
Hardness after quenching is about 65 HRC
Forging
Hot forming temperature: 1050-800°C
Machinability
W1 is a plain carbon steel and machines with ease
Base line of 100% machinability on which machinability of the other tool steels is compared
Corrosion resistance
This is plain carbon steel and it will corrode unless protected
Welding
W1 may be welded by all of the standard techniques
