A709/S355J0W Carbon Steel Coil description
A709 steel coils are composed of a diverse chemical composition, encompassing carbon, silicon, manganese, phosphorus, sulfur, chromium, nickel, and other elements, with a relatively high carbon content typically ranging between 0.22% and 0.29%. This chemical composition contributes to the high strength and wear resistance of A709 steel coils. These coils exhibit excellent mechanical properties, including impressive tensile strength, yield strength, elongation, and impact toughness, ensuring enhanced stability and durability when subjected to loads and impacts. A709 carbon steel coils are commonly utilized as structural and steel processing parts for bridges, railways, ships, vehicles, and machine tools, among other applications.
