Yazan Steel, a trusted manufacturer and supplier based in Amman, Jordan, specializes in high-performance S690 QL sheets and plates. These products are crafted for applications that demand exceptional strength, toughness, and the ability to withstand extreme service conditions. Made from quenched and tempered structural steels, they are designed to provide impressive load-bearing capabilities while keeping material thickness and weight to a minimum. With their excellent weldability and precise dimensions, these sheets and plates are perfect for challenging engineering, construction, and heavy equipment projects where safety and durability are paramount.
S690QL plates and sheets are quenched and tempered, high-strength structural steel with good weldability and toughness. Their chemical composition consists of carbon (≤0.20%), silicon (≤0.80%), manganese (≤1.70%), phosphorus (≤0.025%), sulfur (≤0.015%), chromium (≤1.50%), molybdenum (≤0.70%), nickel (≤2.00%), and boron (≤0.005%). They possess higher mechanical properties, such as a minimum yield point of 690 MPa, tensile strength of 770-940 MPa, and good impact resistance at -40°C. Such features make S690QL steel plates the best fit for heavy-duty applications like machinery, mining, and construction to ensure strength, efficiency, and durability in high-stress conditions.

We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
S690QL plates and sheets are used in a vast array of high-strength, tough, and impact-resistant steel demanding industries. Due to their excellent mechanical properties, they are used in heavyweight applications such as in construction of buildings, mining activities, offshore structures, and machinery production. They are commonly utilized in structural beams, cranes, pressure vessels, bridges, and structural components where weight reduction along with strength are prime requisites. The weldability and toughness of the steel make it an excellent choice for extreme conditions, including cold conditions and high-stress environments. S690QL plates are also employed in the defense, transport, and energy industries to provide better performance, reliability, and safety in demanding industrial applications.
