1018C

1018C refers to a specific grade of low-carbon steel. The designation indicates its nominal composition, with the '10' signifying a plain carbon steel and '18' representing approximately 0.18 percent carbon content. The 'C' further clarifies that it is a carbon steel. This steel is characterized by its excellent ductility, weldability, and machinability, making it a versatile material for a wide range of applications.

Due to its low carbon content, 1018C is relatively soft and does not respond significantly to hardening by heat treatment processes like quenching and tempering. However, it can be case hardened through carburizing. Its strength and hardness are moderate, but it can be readily cold-worked. Common uses for 1018C steel include the manufacturing of shafts, gears, fasteners, linkages, and general structural components where high strength or hardness is not the primary requirement. It is widely available in various forms such as bars, sheets, and tubing.
