FAISAL Steel, based in Muscat, Oman, stands out as a top manufacturer and supplier of high-strength S690QL sheets and plates. Known for their remarkable mechanical properties and outstanding toughness, these plates are crafted using cutting-edge thermomechanical rolling and quenching-tempering techniques, ensuring consistent quality and performance. FAISAL Steel caters to industries that rely on high-strength structural steel, such as construction, heavy engineering, and offshore projects. With a commitment to precision, timely delivery, and robust technical support, the company offers S690QL sheets and plates that adhere to strict standards, delivering reliability and durability in challenging environments.
S690QL sheets and plates are made from microalloyed, low-carbon steels, featuring controlled amounts of manganese, silicon, chromium, nickel, molybdenum, and vanadium. They boast a minimum yield strength of 690 MPa, tensile strength between 720–880 MPa, and an elongation of 11–14%, which translates to excellent fatigue resistance, weldability, and toughness. The quenching and tempering process boosts their notch toughness, making them highly resistant to brittle fractures, even in low-temperature and high-stress situations. These impressive mechanical properties, along with precise dimensions, make S690QL sheets and plates ideal for heavy-duty structural applications.
