JIS S45C Forged Steel Bar / S45C 1045 Forged Round Bars
1.About S45C/1045 Carbon Steel :
C45 steel is a medium tensile steel supplied in the black hot rolled or normalized condition.
It has a tensile strength of 570 - 700 MPa and Brinell hardness ranging between 170 and 210.
C45 steel is characterized by good weldability, good machinability, and high strength and impact properties in either the normalized or hot rolled / forged condition.
