Since its establishment, the company has always adhered to the enterprise spirit of "solid feet and lofty ideals, dare to create and take responsibility, and dedicate to work". After years of careful management, the company has achieved the double improvement of A709 grade HPS70W bridge steel plate capital strength and scale expansion, gained wide recognition and general praise from all walks of life, further realized specialized and large-scale operation and optimized allocation of resources, and effectively improved the A709 grade HPS70W bridge steel plate overall strength, competitiveness and anti risk ability of the company.
15Mo3 steel plate executive standard: DIN 1715515Mo3 steel plate classification: Boiler and pressure vessel steel plateApplication of 15Mo3 steel plate: 15Mo3 steel plate is mainly used to manufacture spherical storage tanks with a capacity of more than 50m3, as well as class II and III vessels such as single-layer roll welding vessels, multi-layer heat sleeve roll welding vessels, A709 grade HPS70W bridge steel plate multi-layer binding vessels and low-temperature pressure vessels.
Weather resistant steel, as a new generation of advanced steel materials, has atmospheric corrosion resistance 2 to 5 times that of ordinary carbon steel. The longer it is used, the more prominent the corrosion resistance. Because it has the characteristics of rust resistance, no coating, thinning and consumption reduction, labor saving and energy saving, weather resistant steel can be applied to steel structures used in buildings, vehicles, bridges, towers and other long-term exposure to the atmosphere, A709 grade HPS70W bridge steel plate and can also be used to manufacture containers and railway Structural components such as vehicles, oil derricks, seaport buildings, and oil platforms.
The allowable working temperature of boiler steel plate is generally below 475 ℃, which can't meet the needs of high temperature working condition. Chromium molybdenum steel is one of the common steels for A709 grade HPS70W bridge steel plate pressure vessels, which is widely used in various hydrogenation units and reforming units in oil refining and chemical industry. Therefore, on the basis of common A709 grade HPS70W bridge steel plate carbon steel, alloy elements such as Cr Mo V are added, which has excellent hydrogen corrosion resistance and good high temperature strength, It is the material of high temperature and high pressure vessel shell and head.
EN 10025-2 steel includes S235 steel (S235JR, S235J0, S235J2), S275 steel (S275JR, S275J0, S275J2), S355 steel (S355JR, S355J0, S355J2, S355K2), S450 steel (S450J0). According to EN 10025-2, the thickness of S450J0 plate is within 3-150mm. The A709 grade HPS70W bridge steel plate, S235 steel, S275 steel and S355 steel plate thickness is ≤250mm. However, the S235J2, S275J2, S355J2 and S355K2 plates limitation is ≤400mm.
