EN 10025-6 high strength steel plates S890Q, S890QL, S890QL1 Description

EN 10025-6 high strength steel plates S890Q, S890QL, S890QL1 are quenching and tempering steel for structures with high strength requirements. The quenched and tempered S890Q, S890QL, S890QL1 high strength steel plates are designed with low carbon equivalent composition and have good weldability. The S890 series steel yield strength is 890 N / mm2 (130 KSI) at least, so they can reduce weight or support higher pressure, thus bearing higher effective load.
