Starrett 54956 Low Carbon Steel Flat Stock Aisi C1018

Product Description

The STARRETT 54956 is a low carbon steel flat stock bar machined to close tolerances for use in fabrication, toolmaking, and general metalworking applications. Manufactured to AISI Type C1018 specification, this flat stock measures 24 inches in length, 2.5 inches in width, and 0.3125 inches in thickness. C1018 is a mild, low carbon steel known for its consistent machinability, weldability, and moderate strength, making it a reliable choice for fixtures, brackets, spacers, and structural components. Thickness and square tolerances are held to plus or minus 0.001 inches, supporting accurate fitment in precision assemblies. The part ships as a single piece per package.

This flat stock is suited for job shop fabrication, maintenance and repair operations, and light structural work in both residential and commercial settings. Typical applications include machine bases, shims, support brackets, and custom fabricated hardware. Machinists, millwrights, and general fabricators working in metal shops, plant maintenance environments, or field fabrication scenarios will find this stock ready to cut, drill, or weld without further surface prep. The 24-inch length accommodates a wide range of cut-to-size applications without excessive waste.
