A709Gr50 steel is a high-strength low-alloy stee. It is widely used in engineering structures, such as building steel structures, construction machinery, mining and mountain machinery, trucks, bridges, pressure vessels, especially for those requiring good weldability and toughness Construction and construction machinery parts. BBNsteel's engineers suggest customer choose low temperature impacting test for steel A709 grade 50 at zero centigree, because these steel plates A709Gr50 normally used in this temperature.
Vanadium is a weak deoxidizer. Adding vanadium into S355J2W hot rolled plate wholesale steel can reduce the adverse effects of carbon and nitrogen, effectively improve the strength, but sometimes also increase the tendency of welding hardening, vanadium is also a commonly used trace alloy element.
The main uses of flat steel are as follows. First, flat steel is used as a raw material for processing steel plates, which is convenient for transportation, takes up a small space, and can save transportation costs. Second, S355J2W hot rolled plate wholesale flat steel can be used as raw material for processing welded pipes. Flat steel can be a finished steel product, or it can be used as a billet for welded pipes and thin slabs for stacked sheets. Third, flat steel can be directly used as a steel structure. As a finished material, flat steel can be used for making hoop iron, tools and mechanical parts, and used as building frame structure and escalator in construction. Fourth, the flat steel has a smooth surface and a certain degree of beauty.
