Starrett 54977 Low Carbon Steel Flat Stock C1018

Product Description

The STARRETT 54977 is a low carbon steel flat stock bar made to AISI Type C1018 specification. It measures 3/8 inch thick, 7 inches wide, and 24 inches long, weighing approximately 17.86 pounds. C1018 is a general-purpose low carbon steel widely used in fabrication, toolmaking, and structural applications where moderate strength and good machinability are required. Dimensional tolerances are tightly controlled: length tolerance is plus 0.625 inches, width tolerance is plus 0.000 to 0.005 inches, and both thickness and squareness tolerances are held to plus or minus 0.001 inches. This stock is suited for shops, machine trades, and fabricators needing ready-to-cut flat bar with consistent geometry.

This flat stock is used across industrial, commercial, and trade applications including HVAC bracket fabrication, plumbing support structures, electrical panel framing components, and general metalworking. Its low carbon content makes it readily weldable, drillable, and machinable with standard shop tooling. It is a common choice when material traceability to an AISI specification is required for a project or job record. Sold individually as a single bar per package.

Installation Notes

Cutting, drilling, and welding of C1018 steel flat stock should be performed by qualified tradespeople using appropriate personal protective equipment including eye and hand protection. Always secure the workpiece in a vise or clamp before cutting or machining. When welding, follow applicable AWS and local code requirements for low carbon steel. Deburr all cut edges before handling or assembly to prevent injury and to ensure proper fit-up.
