Product Description

S45c 1045 Tool Mould Die Steel Hot Rolled Steel Round Bar 
 

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.

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