EN 10025-6 Grade S690QL1 steel quenched and tempered (+QT)

Steel Grade S690QL1 under steel standard EN 10025-6, S690QL1 steel plate is a high strength fine grained quenched and tempered structural steel, offering minimum yield strength of 690 MPa. The low temperature impact test should be carried out below -60 degrees Celsius. The heat treatment of high-strength steel plate S690QL is quenched and tempered. The quenching operation involves cooling the black steel plate faster than in still air. Usually, the black steel plate is tempered after quench hardening or other heat treatment to achieve the required performance.

S690QL1 Steel Plates are used for low-temperature, high-strength key components, construction machinery, mining machinery structures, etc., European standard high-strength steel plates, corresponding to the national standard Q690E Wugang high-strength plates, manufacturing various types of construction machinery, such as mines and various Drilling rigs, electric shovel, electric wheel dump trucks, mining trucks, excavators, loaders, bulldozers, various cranes, coal mine hydraulic supports and other mechanical equipment and other structural parts used for construction of such projects.
