S690Ql is a structural steel with high yield strength in service. The material can be heat treated by quenching and tempering techniques. These EN 10025-6 steel plates have good forming and welding properties.S690QL steel plates have a higher payload capacity and energy efficiency, so they can be used in leaner structures. This steel can also be used in other areas such as heavy transportation, construction, machine building and lifting equipment. We offer customizable products to meet specific customer requirements.
