S690QL is a high-strength quenched and tempered steel grade that meets the EN 10025 specification. The name S690QL stands for a minimum yield strength of 690 MPa. This steel is engineered to deliver high strength, toughness, wear resistance, and excellent weldability for demanding applications.

This steel is popular because its not only strong but also readily available and affordable. Its easy to work with, making it a top choice for both equipment like cranes and lifting machinery, as well as fixed steel structures. Thanks to its strength, engineers can design lighter structures, which means cranes and other machinery can carry heavier loads and operate more efficiently.

Description S690QL is a high yield strength structural steel grade produced in accordance with EN 10025-6. This steel is designed to provide an excellent combination of high strength, toughness, abrasion resistance and weldability. Material/ steel number: 1.8928 Product designation S - Structural steel 690 - Minimum yield strength MPa Q - Quenched and tempered delivery condition L - Impact energy tested at -40C Typical applications S69QL is a very high strength structural steel and can result in greater load-carrying capacities and lighter structures when used in place of conventional structural steels. Uses include earthmoving equipment, dump trucks, mobile cranes, drilling rigs, high-speed fans, and bridges. Chemical composition Mechanical properties Note Chemical composition: Ladle/ product analysis in %max Mechanical properties: At ambient temperature Typical hardness 235-295 BHN: For information purpose only, it is not a requirement for structural steels and therefore not tested Recommended inside bend radii: The values are applicable for bend angles 90 Dimensions and tolerances in accordance with EN 10029 Approximate equivalents ASTM A514, EN 10149-2 Grade S700MC, AS/NZS 3579 Grade 700, AM 700, Bisalloy 80. Fabrication S690QL steel plate can be readily formed or bent at room temperature if adequate power is available and proper procedures are used. Generally, the power required to form S690QL will be three times that required for carbon structural steel. Hot forming Avoid exceeding 560C because the initial tempering can be altered so that the mechanical properties are affected.
