EN10028-6 P690QL2 Boiler Steel Plate
P690QL2 is a high-strength fine grain tempered steel plate, the minimum yield strength of the container steel plate is 690MPa, tensile strength of 770-940MPa. With the large-scale pressure vessels, the application of high-strength steel demand is increasing, with the market demand for larger tank volume, the strength of the steel plate used puts forward higher requirements, high-strength steel plate application, can reduce the tank product quality. The application of high-strength steel plate can reduce the quality of tank products and realize larger product volume.
