The company has formed a production scale of steel plates, steel pipes, steel profiles, and other products, with a planned layout of science, advanced A573 Gr 70 carbon steel plate technology and equipment, reasonable resource allocation, environmental protection, energy saving and high efficiency. BBN company has become a large-scale iron and steel enterprise integrating steel A573 Gr 70 carbon steel plate production, mineral resource development, steel structure and engineering construction, real estate and modern logistics.
Just as A573 Gr 70 carbon steel plate, the boiler steel plate also has strict control of chemical composition for the material, especially harmful elements such as phosphorus and sulfur, and residual elements such as chromium, nickel, and copper; during smelting, good deoxidation and removal of non-metallic inclusions should be carried out to ensure good quality, plasticity and toughness. The organizational structure requires uniformity, and the grain size is controlled within a certain range; there are also strict requirements for surface quality and internal defects. In addition, the boiler steel plate mechanical properties at room temperature and high temperature must be guaranteed.
When pouring the steel with high Mn content, some manganese oxide should be added in the initial slag in advance to prevent the occurrence of the above events. In order to prevent the longitudinal crack of wear-resistant steel plate, A573 Gr 70 carbon steel plate, some measures are often taken to reduce the content of P, S and Se in NM360 wear-resistant steel plate. Strictly control the liquid level fluctuation of the crystallizer; reasonably control the negative sliding time; try to increase the temperature difference of the water in the crystallizer as much as possible.
A573 Gr 70 carbon steel plate, S235JR VS S275JR VS S355JR plates in yield strength: For plate thickness ≤16mm, the min. yield strength of S235JR plates is 235 Mpa, S275JR plates is 275 Mpa, S355JR plates is 355 Mpa. The yield strength of S235JR S275JR S355JR plates reduces with the increasing of plate thickness. S235JR VS S275JR VS S355JR plates in tensile strength: For plate thickness 3-100mm, the tensile strength of S235JR plates is 360-510 Mpa, S275JR plates is 410-560 Mpa, S355JR plates is 470-630 Mpa. For plate thickness 100-150mm, the tensile strength of S235JR plates is 350-500 Mpa, S275JR plates is 400-540 Mpa, S355JR plates is 450-600 Mpa.
