Yousef Steel is a reputable manufacturer and supplier of S1100QL Steel Sheets and Plates based in Riyadh, Saudi Arabia. We specialize in providing top-notch ultra-high-strength structural steel solutions. S1100QL is a quenched and tempered grade specifically designed for critical load-bearing applications that demand maximum strength, durability, and reliability. Our plates are produced to meet strict international standards, ensuring excellent weldability, toughness, and fatigue resistance. Thanks to its impressive strength-to-weight ratio, S1100QL allows for lighter yet stronger structures, making it an ideal choice for advanced engineering projects. At Yousef Steel, we prioritize quality, precision, and timely delivery, confidently serving industries in Saudi Arabia and around the globe.
S1100QL Steel Sheets and Plates are made from alloy steels that include carbon, manganese, silicon, chromium, nickel, molybdenum, and vanadium, all in carefully balanced proportions. They boast an impressive minimum yield strength of 1100 MPa and a tensile strength ranging from 1150 to 1400 MPa, ensuring exceptional performance even in extreme conditions. The quenched and tempered treatment enhances uniformity, toughness, and impact resistance. Despite its ultra-high strength, S1100QL maintains good weldability and machinability, making it a great option for fabrication. Its remarkable mechanical properties offer engineers a dependable solution for lightweight, durable, and demanding structural applications.
