SPV490 plate is a Japanese standard steel plate P355N pressure vessel steel sheet for pressure vessels, which belongs to low alloy high-strength structural steel. It has high strength, good toughness, low welding crack sensitivity and corrosion resistance. SPV490 steel is mainly used to manufacture petroleum storage tanks. Vertical storage tanks are large containers assembled and welded on site. The welding quality of the welds directly determines the efficiency and life of the storage tank. Currently, high-efficiency automatic welding technology is generally used for welding.

The correct choice of billet type, section shape, size and weight are of great significance to P355N pressure vessel steel sheet steel rolling production. Steel rolling production has certain technical requirements for raw materials, such as steel type, section shape, size, weight, and surface quality. The consideration of these technical requirements is necessary to ensure the quality of steel. It should also be specifically considered when determining and selecting the blank. The P355N pressure vessel steel sheet rolling method can be divided into cold rolling and hot rolling according to the rolling temperature.
