ASTM A709 steel plate is a standard specification for bridge structural steel, ASTM A709 steel plate is a carbon, high strength low alloy and quenched and tempered alloy steel. BBN can provide 5 grades of steel plates: A709 Grade36, Grade50, Grade50W, GradeHPS 50W. The atmospheric corrosion resistance indexes of Grade50W, GradeHPS 50W and GradeHPS 70W are all 6.0.
The delivery state of A709Grade36 steel plate is quenched and tempered, and the A709Grade36 steel plate and steel bar are alloy steel structural steel plates.
A709Grade36 steel plate is used in the manufacture of workshops, general construction and various construction machinery, such as drilling rigs, electric shovels, electric wheel dump trucks, mining vehicles, excavators, loaders, bulldozers, various cranes, Coal mine hydraulic support and other mechanical equipment and other structural parts.
A709Grade36 steel plates are used to make road bridges and railway bridges (including cross-sea bridges) with riveted and bolted structures. A709Grade36 steel plates are widely used in engineering structures, such as building steel structures, construction machinery, mining machinery, trucks, bridges, pressure vessels, etc.
A709Grade36 steel plate is especially used for construction and construction machinery parts that require good weldability and toughness.
