    Designation by Standards

    Mat. No. DIN EN AISI
    1.3503 105Cr4 - -

    Chemical Composition (in weight %)

    C Si Mn Cr Mo Ni V W Others
    1.05 0.25 0.33 1.03 - - - - -

    Description
    Low alloyed Cr cold working tool steel.

    Applications
    For balls, rollers, links with diameter up to 10-17 mm. 

    Physical properties (avarage values) at ambient temperature
    Modulus of elasticity [103 x N/mm2]: 210 
    Density [g/cm3]: 7.80

    Soft Annealing
    Heat to 730-760oC, cool slowly. This will produce a maximum Brinell hardness of 207.

    Normalizing
    Temperature: 860-890oC.

    Stress Relieving
    Stress relieving to remove machining stresses should be carried out by heating to 600-650oC, holding for one hour at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.

    Hardening
    Harden from a temperature of 790-820, 820-850oC followed by water or oil quenching or warm bath approx. 400oC. Hardness after quenching is 65 HRC.

    Tempering
    Tempering temperature: 150-170oC.

    Tempering Temperature (oC) vs. Hardness (HRC)

    100oC 200oC 300oC 400oC 500oC 600oC
    64 62 58.5 53.5 47.5 41
