C45 1.0503 forged round bar carbon steel round bar C45 steel bar C45 steel Manufacturer
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.
