Yousef Steel, a leading steel manufacturer and supplier located in Riyadh, Saudi Arabia, proudly offers top-notch **EN 10025-2 S690Q sheets and plates** designed for tough structural applications that demand outstanding strength and durability. S690Q is a high-strength structural steel grade, quenched and tempered, according to the EN 10025-2 standard, providing a minimum yield strength of 690 MPa. These plates find extensive use in heavy construction, bridge building, crane manufacturing, and offshore engineering projects. Yousef Steel ensures precise cutting, exceptional material quality, and tailored solutions to meet the specific needs of industrial and infrastructural clients.
The EN 10025-2 S690Q steel is crafted with a carefully controlled chemical composition, featuring carbon (max 0.22%), manganese (max 1.70%), and alloying elements like chromium, nickel, and molybdenum. This thoughtful composition, along with thermomechanical processing and quenching/tempering treatment, results in remarkable mechanical properties. The steel offers a minimum tensile strength of 740–940 MPa and impressive impact toughness down to -40°C, making it perfect for challenging environmental conditions. It also boasts excellent weldability and good formability, which are crucial for creating large structural components.
