A36 carbon steel round steel-good comprehensive properties and weldability

A36 is a carbon structural steel whose chemical composition and mechanical properties strictly conform to American ASTM standards. A36 steel bar mainly consists of iron, carbon, silicon, manganese, phosphorus, sulfur and other elements. Iron constitutes 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.
