SPV355 steel is a kind of Japanese standard steel for medium temperature pressure vessels. The executive technical standard of SPV355 steel is JIS G3115. SPV355 steel is widely used in petroleum, chemical industry, power station, boiler and other industries. SPV355 steel is used to make reactor, A588 grade K structural steel plate heat exchanger, separator, spherical tank, oil and gas tank, liquefied gas tank, nuclear reactor pressure shell, boiler drum, liquefied petroleum cylinder, high-pressure water pipe of hydropower station, turbine volute and other equipment and components.
As a new type of coil material, compared with the traditional steel coil, A588 grade K structural steel plate, the alloy steel coil and sheet has a great improvement in performance properties. The alloy steel coil and sheet has good thermal strength and oxidation resistance at high temperature. Moreover, the corrosion resistance of alloy steel coil and sheet is better. After long-term corrosion, the service life of traditional coil plate will decrease rapidly, but the new type coil, the alloy steel coil and sheet has strong corrosion resistance, and its service life is far longer than that of traditional coil plate.
Q355GNHE corten steel is characterized by adding a small amount of Cu, P, Cr, Ni and other alloying elements to the steel, so that the steel material forms a dense layer between the rust layer and the substrate with a thickness of about 50 to 100 μm and good adhesion to the substrate metal. The amorphous spinel oxide layer prevents oxygen and water in the atmosphere from penetrating into the steel substrate, slows down the rust development to the steel material, A588 grade K structural steel plate, and greatly improves the steel material's resistance to atmospheric corrosion.
