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.
