Starrett 55027 Steel Flat Stock 24x6x0.75 in Aisi C1018

Product Description

The STARRETT 55027 is a low carbon steel flat stock bar measuring 24 inches long, 6 inches wide, and 0.75 inches thick. Manufactured to AISI Type C1018 specification, this flat stock delivers consistent machinability and weldability suited to fabrication, tooling, and structural 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 tolerances are held to plus or minus 0.001 inches. Machinists, fabricators, and maintenance trades use C1018 flat stock for fixtures, brackets, base plates, wear pads, and general metalworking tasks where precise dimensions and predictable material behavior are required.

This flat stock is well suited to job shop and industrial maintenance environments where raw steel stock is cut, drilled, milled, or welded to produce custom components. Its low carbon content makes it easy to machine and weld without the brittleness concerns associated with higher carbon grades. The 24 x 6 x 0.75 inch bar size is a common choice for larger fixture work, machine bases, and structural reinforcement plates in both light manufacturing and heavy maintenance settings.

Installation Notes

Cutting, drilling, and machining of steel flat stock should be performed by qualified machinists or fabricators using appropriate metalworking equipment and personal protective equipment including eye and hand protection. Secure the workpiece firmly before any cutting or milling operation. When welding C1018 material, follow applicable AWS guidelines and ensure adequate ventilation. Edges and cut surfaces will be sharp after machining and should be deburred before handling or assembly.
