S890Q steel plate is European standard quenched and tempered high yield strength structural steel. S stands for structural steel, Q stands for delivery condition, and 890 is the yield value in MPa. The heat treatment process of S890Q steel plate is Q+T, quenching+tempering, quenching and tempering.
S890Q steel plate is suitable for the manufacture of steel structures such as coal mine hydraulic supports, heavy vehicles, and construction machinery that require good welding performance. Other grades corresponding to S890Q steel plate: Q890C steel plate, Q890D steel plate, S890Q steel plate.
Quenched and tempered high-strength steel is designed with low carbon equivalent composition and has good welding performance. Shot blasting treatment of steel plate before quenching, radiant tube heating of quenching furnace, non-oxidizing atmosphere control and other measures make the steel plate have good surface quality. The design of the special roller table for the quenching machine, the partition water supply cooling, etc., ensure that the mechanical properties of the high-quality steel plate are uniform, and it has a good shape.
S890Q steel plate is used to manufacture all kinds of engineering machinery, such as drilling rigs, electric shovels, electric wheel dump trucks, mining vehicles, excavators, loaders, bulldozers, various cranes, coal mine hydraulic supports and other machinery for mining and various engineering construction equipment and other structures.
