P690QL2 steel plate is a high-strength fine-grained quenched and tempered steel plate. The minimum yield strength of the vessel steel plate is 690MPa, and the tensile strength is 770-940MPa. With the large-scale of pressure vessels, the demand for the application of high-strength steel is increasing. With the market demand for the larger volume of storage tanks, higher requirements are put forward for the strength of steel plates used. The application of high-strength steel plates can reduce the quality of storage tank products and realize the larger volume of products.
P690QL2 steel plate executive standard: EN10028-6.
