Carbon Steel EN-9 Bars and Rods are medium–carbon steel pieces renowned for their superior toughness and wear resistance properties. The standard composition entails Carbon (0.35–0.45%), Manganese (0.60–0.90%), with maximum restrictions of Phosphorus (0.05%) and Sulphur (0.05%). These EN-9 bars offer 650–850 MPa tensile strength and yield strength of approximately 350 MPa, good machinability, and hardenability. Because of their optimum combination of strength and workability, EN-9 bars are found to be ideal for use where good mechanical performance under heavy stress and friction is required.
