A36/Q235/S235JR Carbon Steel Coil Description
A36 steel coil is mainly composed of iron, carbon, silicon, manganese, phosphorus, sulfur and other elements. Iron is the most dominant component, constituting more than 99% of the entire chemical composition. Its carbon content proportion is relatively high, around 0.2%, ensuring that the steel has a certain hardness and toughness. The addition of silicon, manganese and other elements enhances the strength and toughness of steel. The content of elements such as phosphorus and sulfur is low to ensure that the steel coil has good welding performance and corrosion resistance. A36 steel coil has excellent mechanical properties, and its tensile strength, yield strength, elongation and impact toughness are all higher than ordinary steel.
