For quenching and tempering, parts for machine building and vehicles.
Physical properties (average values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 200
Density [g/cm3]: 7.85
Thermal conductivity [W/m.K]: 51.2
Specific heat capacity[J/g.K]: 0.486
Soft Annealing
Heat to 650-700oC, cool slowly.
Normalizing
Temperature: 880-920oC.
Hardening
Harden from a temperature of 860-900oC followed by water quenching.
