Application of Q690E steel plate for high-strength welded structure

As a high-strength welded structural steel plate, Q690E has excellent weldability. Q690E steel plate executive standard: GB/T16270, GB/T1591.

Q690E steel is a low-temperature resistant high-strength steel with a yield strength of 690Mpa, "Q" represents the yield strength, 690 represents the yield strength value, and "E" represents the quality grade of the steel plate. The Q690 steel grades are A, B, C, D, E. Among them, the impact temperature of Q690 grade E steel plate is -40℃ Q690E steel plate has higher yield strength and tensile strength. Q690E steel is generally applied to engineering machinery.

Q690E steel plate uses:
Q690E steel plate corresponds to European standard S690QL, which is a -40℃ impact high-strength quenched and tempered steel plate. It is used to manufacture all kinds of construction machinery with resistance to low temperature impact, such as drilling rigs, electric shovels, electric wheel dump trucks, mining trucks, excavators, loaders, bulldozers, various cranes, coal mine hydraulic supports and other machinery used in mines and various engineering constructions.
