SPV490Q steel plate has high strength, good toughness, low welding crack sensitivity and corrosion resistance. This 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. In recent years, SPV490Q steel has been increasingly used as the main plate of the storage tank in the construction of large storage tanks.
