S690QL1 high yield strength steel plate is a high-strength, low-alloy structural steel, especially in the quenching + tempering state, which has high comprehensive mechanical properties. S690QL1 steel plate has the characteristics of high strength, low temperature toughness, welding performance and corrosion resistance. S690QL1 steel is mainly used to manufacture engineering machinery, mining machinery, construction machinery, lifting machinery and other mechanical parts that are resistant to low temperature, high load and heavy impact.
S690QL1 non-alloy structural steel plate implements the European standard EN10025-6, S: stands for Structural Steel. 690: Indicates that the minimum yield strength of the steel is 690 MPa. Q: Indicates that the steel is delivered in a quenched and tempered state. L1: Indicates the quality grade of the steel, where L1 represents the minimum tensile strength of 770-940MPa.
S690QL1 quenched and tempered structural steel has the same standard grade as S690Q and S690QL, which are mainly used in large ships, bridges, power station equipment, medium and high-pressure boilers, high-pressure vessels, rolling stock, hoisting machinery, mining machinery and other large-scale welding Structure.
