S690QL is a quenched and tempered high-yield structural steel, perfect for projects that demand outstanding strength, durability, and toughness. Catering to various industries like construction, mining, transportation, and heavy machinery, Yousef Steel guarantees reliable performance, timely deliveries, and a customer-centric approach, making them the go-to partner for high-performance steel across Saudi Arabia and the GCC.
S690QL is a robust, quenched and tempered structural steel grade. Its chemical makeup features carbon, manganese, chromium, molybdenum, nickel, and trace amounts of boron, all of which boost hardenability, toughness, and weldability. With a minimum yield strength of 690 MPa and tensile strength ranging from 770 to 940 MPa, S690QL showcases impressive impact resistance, even in colder conditions. Its low carbon equivalent and refined grain structure contribute to excellent weldability. These characteristics make S690QL an ideal choice for reducing weight in structural applications while maintaining strength and performance in challenging environments.
