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 double improvement of A709 Gr 50 bridge steel plate 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 A709 Gr 50 bridge steel plate overall strength, competitiveness and anti risk ability of the company.
A709 Gr 50 bridge steel plate surface cracks refer to the linear cracks on the surface of A709 Gr 50 bridge steel plate, which should generally be the same as the forging or rolling direction. Formation reason: it is mainly due to the hairline, hot crack and cold crack caused by surface over burning, decarburization, looseness, deformation and excessive internal stress during processing (forging, rolling, heat treatment, quenching and tempering), as well as the high content of sulfur and phosphorus impurities on the surface. Inspection method: A709 Gr 50 bridge steel plate surface cracks can be detected by naked eye observation, acid pickling, magnetic particle inspection, coloring inspection and metallographic method.
Compared with A709 Gr 50 bridge steel plate, ordinary steel plate, ship plate has better resistance to wind and wave. In the ocean, there are often big winds and big waves. If the performance advantage of ship plate is not prominent, it is easy to be damaged by big waves. The service life of ship plate is longer than that of ordinary steel plate. Because of its excellent performance, the ship plate can be used for a long time. Some waste ships can remove the ship plate for recycling. The price of ship plate is higher than ordinary steel plate.
Weathering steel is made of ordinary carbon steel with a small amount of copper, nickel and other corrosion-resistant elements. It has the characteristics of high-quality steel such as toughness, plastic extension, forming, welding and cutting, abrasion, high temperature and fatigue. A709 Gr 50 bridge steel plate, Weathering steel sheets are used to manufacture containers, railway vehicles, oil derricks, harbour buildings, oil production platforms and containers containing hydrogen sulfide corrosive media in chemical oil equipment.
A709 Gr 50 bridge steel plate product plate specification range:Thickness 3-150mmWidth 1500-4020mmLength 4000mm-17000mmHeat treatment: annealing, or normalizing and tempering
