When it comes to Carbon Steel AISI 1018 Bars and Rods, you can expect them to contain about 0.18% carbon, 0.60–0.90% manganese, along with trace amounts of phosphorus and sulfur, with the rest being iron. This low carbon content gives them excellent machinability, weldability, and formability. Mechanically, AISI 1018 boasts good tensile strength, moderate yield strength, and decent elongation, making it reliable in both cold-worked and hot-worked conditions. It also responds well to carburizing processes, which enhances surface hardness while keeping the core ductile and tough—ideal for parts that need both strength and machinability.
