Al Summan Metals delivers precision-engineered steel solutions that combine toughness, machinability, and enduring performance, making them a preferred option for high-stress and heavy-duty applications.
Carbon Steel EN-31 R-100 Bars are high-carbon, chromium-alloyed steels containing roughly 1.00–1.10% carbon, 1.25–1.65% chromium, 0.30–0.60% manganese, together with trace amounts of phosphorus and sulfur. This distinctive combination provides them with exceptional hardness, wear resistance, and strength. From a mechanical standpoint, EN-31 R-100 steel offers a tensile strength of about 900–1100 MPa and a yield strength of 600–800 MPa. The material is recognized for its outstanding toughness, machinability, and fatigue resistance, and it can be hardened and tempered for precision tool and die applications.
