Aatir Steel is a reliable manufacturer and supplier of S690QL Steel Sheets and Plates based in Cairo, Egypt. They specialize in ultra-high-strength structural steel products that are perfect for tough industrial and construction projects. These S690QL Plates are crafted using advanced quenching and tempering techniques, which give them outstanding tensile strength, toughness, and weldability. Aatir Steel guarantees that every plate adheres to international standards like EN 10025-6, ensuring you get dependable, precise, and consistently high-quality products. These plates are perfect for applications that need thinner materials without sacrificing strength, making them popular in heavy machinery, cranes, bridges, and structural frameworks. Aatir Steel delivers robust, high-performance S690QL steel solutions for all your industrial and engineering needs.
S690QL Steel Sheets and Plates are made from low-alloy, high-strength steels that include carbon (≤0.20%), manganese (≤1.70%), silicon (≤0.80%), chromium (≤1.50%), nickel (≤2.00%), and molybdenum (≤0.70%). They boast a minimum yield strength of 690 MPa and a tensile strength ranging from 730 to 880 MPa. These plates are known for their excellent impact toughness, fatigue resistance, and weldability, even at ultra-high strength levels. The quenched and tempered microstructure ensures dimensional stability, high hardness, and wear and stress resistance, making them ideal for critical load-bearing, structural, and high-stress engineering applications.
