Description
Structural Cr-Mo-V-steel.

Applications
Severely stressed springs for automobile industry - machine and engine parts, torsion springs, threaded springs, bark removing knives.

Physical properties (avarage values) at ambient temperature
Modulus of elasticity [10³ x N/mm²]: 210
Density [g/cm³]: 7.78

oft Annealing
Heat to 640-680^oC, cool slowly. This will produce a maximum Brinell hardness of 255.

Normalizing
Temperature: 850-880^oC.

Hardening
Harden from a temperature of 830-860^oC followed by oil quenching.

Tempering
Tempering temperature: 350-550^oC.
