Product Description
ASTM A709 steel plate is in accordance with the standard specification for bridge structural steel, ASTM A709 steel plate is a carbon, high strength low alloy and quenched and tempered alloy steel mainly used in bridge construction. The chemical composition of A709 steel plate s mainly includes carbon, silicon, manganese, phosphorus, sulfur, chromium, nickel and other elements. The carbon content is relatively high, generally between 0.22% and 0.29%. This chemical composition ratio gives A709 steel plate s high strength and wear resistance. In terms of mechanical properties, A709 steel plates have very good tensile strength, yield strength, elongation and impact toughness, ensuring that the A709 steel plates have better stability and durability when bearing load and impact. A 709 carbon steel plates are commonly used as structure/steel processing parts for bridges, railways, ships, vehicles, machine tools, etc. .
