Description
Cold work steel/" target="_blank" class="keylink">tool steel.
Applications
Steel used for water hardened machine spanners, screw spanners, screwdrivers.
Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 210
Density [g/cm3]: 7.85
Continuous Cooling Transformation (CCT) Diagram
Time-Temperature Transformation (TTT) Diagram
Soft Annealing
Heat to 680-720oC, cool slowly. This will produce a maximum Brinell hardness of 220.
Hardening
Harden from a temperature of 830-860oC followed by water quenching. Hardness after quenching is 52-55 HRC.
Tempering
