The Performance requirements of low alloy structural steel, A283 Gr D CS steel carbon plate:(1) High strength: generally, the yield strength is above 300Mpa.(2) High toughness: the elongation is required to be 15% - 20%, and the room temperature impact toughness is greater than 600kJ/m ~ 800kJ/m. For large welded components, higher fracture toughness is required.(3) Good weldability and cold forming property.(4) Low cold brittle transition temperature. (5) Good corrosion resistance.
The difference between cold rolled steel sheet and hot rolled steel plate. The carbon content of A283 Gr D CS steel carbon plate, hot rolled steel plate is slightly higher than that of cold rolled steel sheet. In the case of little difference in composition, the density of cold rolled steel sheet and hot rolled steel plate is the same. Hot rolled steel plate has characteristics of low hardness, easy processing and good ductility. Cold rolled steel sheet has high hardness, and it is relatively difficult for processing. But it is not easy to deform and has high strength. Hot rolled steel plate can be made into alloy steel plate by adding other elements, and its properties are also excellent compared with other high-quality steel plates.
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 duble improvement of 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 overall strength, competitiveness and anti risk ability of the company.
Affected by the weak futures performance and weak spot follow-up, the steel billet price is temporarily stable. The overall growth trend of China's A283 Gr D CS steel carbon plate is slowing down, and the demand in the north is lower than that in the south. Under the background of economic recovery, the demand toughness still exists, the resource inventory is tight, and the actual willingness of the spot merchants to let the price is not obvious. The price of A283 Gr D CS steel carbon plate is expected to be adjusted and operated stably.
