S890QL1 High Strength Steel Plate
S890QL1 is a high-strength steel plate that belongs to the Quenched and Tempered (Q&T) steel category. It is specifically designed to provide excellent strength and toughness in various demanding applications, such as construction machinery, mining equipment, and offshore structures.
The "S" in S890QL1 stands for structural steel, while the number "890" refers to the minimum yield strength in MPa. In this case, it means that the steel has a minimum yield strength of 890 MPa.
The "QL1" indicates that the steel is quenched and tempered to achieve its high strength properties. The quenching and tempering process involves heating the steel to a high temperature and then rapidly cooling it in water or oil (quenching) to harden it. Afterward, the steel is reheated to a lower temperature and held for a specific period of time (tempering) to improve its toughness and reduce brittleness.
