SPV490 plate is a Japanese standard steel plate A514 grade B structural steel material 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.
16Mo3 alloy are featured by the good heat resistance and corrosion resistance. 16Mo3 steel plate chemical composition(%):C: 0.12 ~ 0.2 Si: ≤0.35 Mn: 0.4 ~ 0.9 P: ≤0.025 S: ≤0.01 Cu: ≤0.3 Ni: ≤0.3 Cr: ≤0.3 Mo: 0.25 ~ 0.35 Al: ≥0.02 N: ≤0.012. 16Mo3 alloy steel mechanical properties:Yield strength (MPa) 372MPa, Tensile strength (MPa) 350MPa, Elongation (%) ≥22. Impact temperature (℃) 20, Impact energy value (J) 335J / cm². A514 grade B structural steel material, 16Mo3 steel plate is widely used in petroleum, chemical, power station, boiler and other industries.
Weathering steel plate for welding structure is made by adding metal materials such as chromium, molybdenum, titanium and vanadium to ordinary molten steel. The addition of these materials can form a protective film on the steel surface, which can resist weathering corrosion for a long time. The advantages of weathering steel plate for welding structure: It has very good welding performance and weather resistance, and is widely used in railways, bridges and other areas that need to be exposed to the atmosphere for a long time. Disadvantages of weathering steel plate for welded structure: It has very high requirements on the production process, and the poorer technology can not produce good weathering steel plate, A514 grade B structural steel material.
