    Description
    Unalloyed carbon steel.

    Applications
    Quenched and tempered steel for heavy duty parts in machines, vechicles.

    Physical properties (avarage values) at ambient temperature
    Modulus of elasticity [103 x N/mm2]: 210
    Density [g/cm3]: 7.85

    Soft Annealing
    Heat to 680-710oC, cool slowly. This will produce a maximum Brinell hardness of 183.

    Hardening
    Harden from a temperature of 790-820oC followed by water. Hardness after quenching is 63-64 HRC.

    Tempering
    Tempering temperature: 180-300oC.

    Forging
    Hot forming temperature: 1100-850oC.

    Machinability
    No data.
