Starrett 54989 C1018 Steel Flat Stock 24x2.5x0.5 in

Product Description

The STARRETT 54989 is a cold-finished, low carbon steel flat bar cut to 24 x 2.5 x 0.5 inches and manufactured to AISI Type C1018 material specification. This flat stock provides machinists, fabricators, and tool-and-die workers with a reliable, dimensionally consistent bar for layout, fixturing, tooling, and general structural applications. Thickness tolerance holds to plus or minus 0.001 inches, squareness tolerance matches that same value, and width tolerance runs plus 0.000 to 0.005 inches, making it suitable for precision work that demands tight dimensional control. The 24-inch nominal length includes a positive length tolerance of plus 0.625 inches, so the bar arrives at or above specified length.

This flat stock is commonly used in machine shops, maintenance and repair operations, and light fabrication environments. Typical applications include making jigs, fixtures, brackets, and spacers where weldability and machinability are required. AISI C1018 is one of the most machinable low carbon steels available, responding well to drilling, milling, turning, and welding without special preheat requirements. It is not intended for hardening applications. Trade professionals in metalworking, industrial maintenance, and millwright work routinely stock this size for on-demand stock removal and custom part fabrication.

Installation Notes

Cutting, drilling, and welding should be performed by qualified machinists or fabricators using appropriate tooling and personal protective equipment. Secure the workpiece firmly before any machining or cutting operation. Edges may be sharp as received — deburr before handling or assembly. Follow applicable shop safety standards and local codes for metalworking operations.
