1. Excellent comprehensive mechanical properties
S355 offshore structural steel plate has high strength, yield strength of not less than 355MPa, tensile strength of 470MPa - 630MPa, providing strong support for offshore structures. Its good toughness can cope with the impact of the complex marine environment, not easy to break. Higher elongation gives good plastic deformation ability, adapt to a variety of complex stress situations in the ocean, to ensure that the marine engineering structure in the harsh environment of stable operation.
2. excellent welding performance
In the construction of marine engineering, welding is crucial, S355 steel plate welding performance is excellent, adapt to a variety of welding processes, welded joints with high strength and stable quality, to ensure the integrity and safety of marine structures. Whether manual or automated welding, show good adaptability, provide strong support for the efficient construction of marine engineering.
3. excellent processing performance
S355 steel plate processing performance is excellent, cutting, bending and other processing methods can be easily carried out. Meet the requirements of different marine engineering structure design and manufacturing, to provide more creative space for designers. In actual construction, improve construction efficiency and reduce project costs.
4. a reasonable chemical composition
S355 steel mainly contains carbon, silicon, manganese and other elements. Carbon content in 0.14% - 0.22%, the right amount of carbon to provide strength, but too high impact on toughness and welding performance. Silicon content of 0.20% - 0.60%, to improve strength and oxidation resistance. Manganese content of 1.00% - 1.60%, improve strength and toughness, reduce cold brittleness. Strictly control the content of phosphorus, sulfur and other harmful elements to ensure stable quality and performance.
5. Wide applicability
S355 series offshore structural steel plate has wide applicability and is the ideal choice in the field of offshore engineering. In the construction of offshore and deep-sea oil production platforms, it is subject to huge pressure and complex environmental loads. For FPSO vessels, high strength and good corrosion resistance to ensure safety and reliability, Spar platforms require high material properties, S355 steel plate comprehensive performance to meet the needs. Coastal power plants and terminal facilities and other ocean-related projects, can also play an important role in providing stable structural support.
In short, S355 marine engineering structural steel plate with excellent comprehensive mechanical properties, excellent welding performance, excellent processing performance, reasonable chemical composition and wide applicability, in the field of marine engineering occupies an important position, for the development and utilization of marine resources to provide a reliable material security.
