Starrett 54943 Low Carbon Steel Flat Stock C1018

Product Description

The STARRETT 54943 is a low carbon steel flat stock bar made to AISI Type C1018 material specification. This flat bar measures 24 inches long, 3.5 inches wide, and 0.25 inches thick, weighing approximately 5.96 pounds. C1018 is a general-purpose low carbon steel known for its consistent machinability, weldability, and moderate strength, making it a reliable choice for fabrication, repair, and tooling applications. Tolerances are tightly held: length tolerance is plus 0.625 inches, width tolerance is plus 0.000 to 0.005 inches, and both thickness and square tolerance are plus or minus 0.001 inches. Machinists, fabricators, and maintenance technicians rely on this stock for precision fitment work.

This flat stock is suited for use in light fabrication, machine shop work, maintenance and repair operations, and custom fixture building. Its low carbon content makes it easy to cut, drill, and weld without requiring specialized tooling or preheat procedures. It is commonly used in industrial, commercial, and trade settings where a dimensionally consistent steel flat bar is needed for brackets, spacers, wear plates, or structural reinforcement components.
