When it comes to composition, Carbon Steel AISI 1018 Bars mainly consist of carbon (0.15–0.20%), manganese (0.60–0.90%), along with trace amounts of phosphorus and sulfur. This blend results in a low-carbon steel that boasts excellent weldability and ductility. These bars deliver a minimum tensile strength of 440 MPa, a yield strength of around 370 MPa, and an elongation of 15–20%, which contributes to their toughness and wear resistance. They also respond favorably to carburizing and heat treatment processes, which enhance surface hardness while keeping the core ductile. These characteristics make AISI 1018 bars perfect for both cold- and hot-forming operations.
