Carbon Steel EN-8 Bars are medium-carbon steel bars that typically contain 0.35–0.45% carbon, 0.60–1.00% manganese, up to 0.10–0.35% silicon, and trace amounts of phosphorus and sulphur. These bars have a yield strength of about 450 MPa and a tensile strength of 550–700 MPa. EN-8 steel is appropriate for parts needing high strength and wear resistance because of its good ductility and shock resistance. The material offers exceptional machinability for precision engineering applications and can be heat-treated to improve mechanical qualities like hardness and toughness.
