Starrett 55007 Low Carbon Steel Flat Stock Aisi C1018

Product Description

The STARRETT 55007 is a low carbon steel flat stock bar measuring 24 inches long, 2.5 inches wide, and 0.625 inches thick, manufactured to AISI Type C1018 material specification. This cold-finished flat bar delivers tight dimensional tolerances, including plus or minus 0.001 inches on both thickness and squareness, making it well suited for precision layout work, tooling fixtures, and general fabrication tasks. Weighing 10.62 pounds per piece, it provides the mass and rigidity required for structural and mechanical applications. Machinists, fabricators, and tool-and-die tradespeople will find this bar stock ready for sawing, drilling, milling, or welding without additional material prep.

This flat stock is used in a wide range of industrial and trade fabrication settings, including machine shops, maintenance facilities, and manufacturing environments. Typical applications include custom brackets, fixture plates, wear strips, jigs, and general structural components where moderate strength and excellent machinability are required. C1018 low carbon steel is well regarded for its weldability and ease of machining compared to higher-carbon alloys, making it a common choice when parts require threading, tapping, or close-tolerance turning. Sold as a single piece per package.

Compatibility

Designed as a general-purpose flat bar stock for use in fabrication, tooling, and maintenance repair applications where AISI C1018 low carbon steel and this exact cross-section are specified.

Installation Notes

Cut, drill, or machine using tooling rated for low carbon steel. Secure the bar firmly in a vise or fixture before cutting to prevent movement. Deburr all machined edges before final assembly to avoid injury and ensure proper fit. Welding should follow standard procedures for low carbon steel in accordance with applicable AWS guidelines.
