SPV490 plate is a Japanese standard steel plate RA hull construction 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 China's RA hull construction steel market economy, the company vigorously implements the strategy of industrialization, internationalization and diversification, promotes group operation, intensive development and lean management, and builds the company into a company with scientific development concept, continuous innovation vitality, excellent corporate culture and strong sense of social responsibility through rich series of RA hull construction steel products and project portfolio and complete operation network And international first-class competitiveness of modern enterprises.
Semi-endless rolling technology has three advantages: the RA hull construction steel product's limit thickness and limit width specification range has been significantly expanded. The thinnest thickness of SPHC steel has been expanded from 1.0 mm to 0.78 mm, and the limit specification product width has been expanded from 1100 mm to 1300 mm; The thinnest thickness of Q235B steel has been expanded from 1.2 mm to 1.0 mm, and the width range of the limit specification products has also been further expanded.
After hot extrusion, the grains of the alloy wear-resistant steel plate are significantly refined, dendrites and network structures are broken, and the grain size and the distribution of precipitated phases in the alloy are more uniform to generate Al2Y and Al3Y phases distributed within and along the grain boundaries , The hardness is significantly improved, the mechanical properties are significantly improved, the deformation strengthening effect is more significant, and the corrosion resistance of the RA hull construction steel, alloy wear-resistant steel plate is significantly improved.
