Product Details

A709/S355J0W Carbon Steel Coil Description

A709 steel coil has a very diverse chemical composition including 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 coils high strength and wear resistance. In terms of mechanical properties, the coils have very good tensile strength, yield strength, elongation and impact toughness, ensuring they have better stability and durability when bearing load and impact. A709 carbon steel coils are commonly used as structure/steel processing parts for bridges, railways, ships, vehicles, machine tools, etc..
