    Steel C45 Round Baris
    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.

    C45 round bar steel is equivalent to EN8 or 080M40.
    Steel C45 bar or plate issuitable for the manufacture of parts such as
    gears, bolts, general-purpose axles and shafts, keys and studs.

          5. Forging of Carbon Steel C45 Round Bar

          Hot forming temperature: 850-1200oC.

          Pre
          heat to 750 oC – 800 oC, then continue heating to 1100 oC – 1200 oC
          maximum, hold until temperature is uniform throughout the section and
          commence forging immediately. Forging is not workable below 850 oC.
          Finished forgingscould be air cooled.

          We are strong on forged steel C45 round bar. Welcome enquiry of C45 steel materials.

          7. Hardening of DIN C45 Steel 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.
