Product Description
S45C C45E/1.1191 1045 Hot Rolled Steel
1: AISI 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.
