A709 Grade 50 Low Alloy Steel Plate

 

ASTM A709 is the standard specification for structural steel for bridges and covers carbon steel, high-strength low-alloy steel, and quenched and tempered alloy steel used as structural plates in bridge construction. GNEE offers the following five grades of A709: 36, 50, 50W, HPS 50W, and HPS 70W.

 

The "A" in A709 Grade 50 high tensile steel plate stands for American standard alloy steel, "709" is the identification code of this series of steel plates, and "Grade 50" stands for the grade of the steel plate.

 

A709 Grade 50 low alloy steel has good impact toughness by adding alloy elements and proper heat treatment.

 

A709 Grade 50 low alloy steel material is widely used in engineering structures such as building steel structures, construction machinery, mining machinery, heavy trucks, bridges, pressure vessels, etc., especially for construction and engineering machinery parts that require good weldability and toughness.
