ASTM A709 Gr.50 material is a kind of carbon and high-strength low alloy steel structural shapes, plates and bars, and quenched and tempered alloy steel for structural plates intended for use in bridges.
ASTM A709 Gr.50 alloy also maintains excellent corrosion resistance, allowing it to maintain long lifespans–even during the most harsh atmospheric conditions. These properties make A709 ideal for applications such as bridges. ASTM A709 Gr.50 high strength low alloy steel is a standard material employed by the American Association of State Highway and Transportation.
ASTM A709 Gr.50 steel maintains tensile yield strength of 50,000 psi and an ultimate tensile strength of 65,300 psi. It is also highly weldable and can produce excellent quality welded joints. The A709 Gr.50 high-strength low alloy steel can be supplied in I-Beams, Structural Angles, Wide Flange Beams, Steel Plates, Structural Steel Channels.
The A709 alloy, which is composed of iron, manganese, carbon, and other elements, maintains an excellent strength-to-weight ratio. This means that smaller quantities of steel are required in order to meet our customer’s varying strength requirements, improving efficiency and cutting down on excess weight.
