Al Summan Metals provides precision-engineered steel solutions that combine toughness, machinability, and enduring performance, positioning them as the preferred option for challenging industrial and mechanical applications.
Carbon Steel EN-9 Bars are medium-carbon steels that generally hold about 0.36–0.44% carbon, 0.60–0.90% manganese, together with small quantities of phosphorus and sulfur. This distinctive composition delivers a balanced combination of strength, toughness, and resistance to wear. In terms of mechanical properties, EN-9 steel offers a tensile strength of roughly 600–700 MPa and a yield strength between 355–450 MPa. It is recognized for its good machinability, moderate ductility, and excellent hardness, and it can undergo heat treatment to enhance its mechanical performance in demanding engineering uses.
