SPV490 plate is a Japanese standard steel plate EN10025-4 S355ML steel 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.

With the development of science, technology and industry, higher requirements are put forward for steel materials, such as higher strength, resistance to high temperature, high pressure, low temperature, corrosion resistance, abrasion, and other special physical and chemical properties. EN10025-4 S355ML steel, carbon steel can no longer fully meet the requirements, so alloy steel plates appeared. Improving the strength of steel is one of the main purposes of adding alloying elements.

Steel plate cutting and machining parts are mainly used in machinery manufacturing, ships building, landscape building, petroleum storage tanks, steel structures and mold processing industries. We can provide finished and semi-finished EN10025-4 S355ML steel steel plates products according to the client needs. Realize the service from product drawings-steel plate procurement-steel plate cutting-steel plate processing EN10025-4 S355ML steel steel plate distribution services, so as to save customers manpower and material resources.
