Starrett 55040 Low Carbon Steel Flat Stock 24x6x0.875in

Product Description

The STARRETT 55040 is a low carbon steel flat stock bar measuring 24 inches long, 6 inches wide, and 0.875 inches thick. Manufactured to AISI Type C1018 specification, this cold-finished flat bar delivers consistent dimensional accuracy with a thickness tolerance of plus or minus 0.001 inches and a width tolerance of plus 0.000 to 0.005 inches. Length tolerance is held to plus 0.625 inches. Weighing 35.7 pounds, this flat stock is suited for fabrication, machining, and structural applications where tight tolerances and predictable material properties are required. Machinists, fabricators, and metalworking tradespeople rely on C1018 for its good machinability and weldability.

This flat stock is used in general industrial and trade fabrication settings, including machine shops, maintenance and repair operations, and light structural fabrication. The 24 x 6 x 0.875 inch format is well suited for cutting down into brackets, wear plates, spacers, and other flat components. Its low carbon content makes it compatible with standard welding and bending processes without requiring preheating in most shop conditions.

Installation Notes

Cutting, drilling, or welding of steel flat stock should be performed by qualified metalworkers or machinists using appropriate personal protective equipment. Secure the workpiece with proper clamping before machining or cutting operations. Follow applicable OSHA and shop safety standards when handling heavy flat bar stock at 35.7 pounds per piece. Edges and cut surfaces may be sharp — deburr after any secondary operations.
