This specific type of steel is a low-carbon, general-purpose material known for its good machinability, weldability, and ductility. The “1018” designation refers to its chemical composition, specifically the presence of approximately 0.18% carbon. Cold rolling, a manufacturing process performed at or near room temperature, enhances its strength, surface finish, and dimensional tolerances compared to hot-rolled steel. This results in a smoother, more precise product suitable for various applications.
The balance of properties achieved through its composition and processing makes this material highly versatile. It finds widespread use in components requiring moderate strength and good workability, such as shafts, pins, spindles, and structural members in non-critical applications. Its historical prevalence is rooted in its reliable performance and cost-effectiveness, making it a staple in many industries. The enhanced properties resulting from cold rolling contribute to its suitability for parts requiring tighter tolerances and improved surface quality.
