S890QL1 high strength steel plate
S890QL1 high strength alloy steel is a tempered, high yield strength structural steel of European standard. Where "S" denotes structural steel, "890" is the yield value (in MPa), "Q" denotes the delivery condition, and "L1 "Q" indicates the delivery conditions, "L1" indicates the minimum value of impact work specified at a temperature not lower than -60℃.
S890QL1 high strength low alloy structural steel has good welding performance and is mainly used in high-strength mechanical engineering aspects, such as wear-resistant mining machinery industry.
