When it comes to composition, Carbon Steel AISI 1018 Bars and Rods are primarily made of iron, with about 0.15–0.20% carbon, along with trace amounts of manganese (0.60–0.90%) and phosphorus/sulfur. This low-carbon steel grade is celebrated for its excellent weldability and machinability. On the mechanical side, it boasts a tensile strength of around 440 MPa and a yield strength of 370 MPa, with an elongation of roughly 15–20%. Its Brinell hardness falls between 126 and 140. These characteristics make AISI 1018 steel a go-to choice for parts that need precision and a smooth surface finish, all while maintaining strength and ductility.
