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.
