Mat.No. 1.2833, DIN 100V1, AISI W2

Designation by Standards

Chemical Composition (in weight %)

Description
Low alloyed water-hardening tool steel.

Applications
Cold working tools for steels and metals when hard surface and tough core are demand; tap drills, dies, broaching tools, stone working tools.

Physical properties (avarage values) at ambient temperature
Modulus of elasticity [10³ x N/mm²]: 190-210
Density [g/cm³]: 7.85
Thermal conductivity [W/m.K]: 14.4
Electric resistivity [Ohm mm²/m]: 0.20
Specific heat capacity[J/g.K]: 0.46

Soft Annealing
Heat to 680-720^oC, cool slowly. 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^oC, 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^oC followed by water quenching. Hardness after quenching is 65 HRC.

Tempering
Tempering temperature: 100-200^oC.

Forging
Hot forming temperature: 1000-800^oC.

Machinability
No data.

Corrosion Resistance
Corrosion resistance of this alloy is better than that of plain carbon steels. However it will rust unless given protective treatment.
