Product Description
C45 Forged Steel Round Bar / S45C Steel Forged Round Bars
1.About 1045Carbon Steel :
AISI 1045 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.
AISI 1045 steel is characterized by good weldability, good machinability, and high strength and impact properties in either the normalized or hot rolled / forged condition.
