    1: 1045 steel introduction
        Steel C45 Round Bar is an unalloyed medium carbon steel, which is also a general carbon engineering steel. C45 is a medium strength steel with good machinability and excellent tensile properties. C45 round steel is generally supplied in the black hot rolled or occasionally in the normalised condition, with a typical tensile strength range 570 - 700 Mpa and Brinell hardness range 170 - 210 in either condition. It does not however respond satisfactorily to nitriding due to a lack of suitable alloying elements.

    4: 1045 steel mechanical properties  

        The mechanical properties mainly include tensile strength, yield strength, elongation, area or reduction, hardness, impact value, non-metalic inclusion etc. Different heat treatment, the mechanical properties will be different, such as normalized, tempered, QT. If you want to know the properties, kindly contact the salesman.

    6: Hardening
        Harden from a temperature of 820-860oC followed by water or oil quenching.
        Heat to 820 oC – 850 oC hold until temperature is uniform throughout the section, soak for 10 – 15 minutes per 25mm of section, and quench in water or brine. Or,
        Heat to 830 oC – 860 oC soak as above and quench in oil.Temper immediately while still hand warm.

    7: Delivery condition
        For hot forged  bar, usually the delivery condition is hot forged, annealed/QT, rough turned/Black surface.
        For hot rolled bar, usually the delivery condition is hot rolled, annealed/QT, Black surface.
        For Cold Drawn bar, usually the delivery condtion is cold drawn, annealed/QT, peeled/black surface
        For hot rolled plate, usually the delivery condition is hot rolled, annealed, milled/black surface
        For hot forged plate, usually the delivery condition is hot forged, normalized/annealed, milled/black surface.
