Starrett 55068 Low Carbon Steel Flat Stock C1018

Product Description

The STARRETT 55068 is a low carbon steel flat stock bar made to AISI Type C1018 material specification. It measures 24 inches in length, 2.5 inches in width, and 1.5 inches in thickness, with a finished weight of 25.5 pounds. C1018 is a mild, machinable steel commonly used in structural fabrication, fixture building, and general metalworking applications where weldability and moderate strength are required. Close-tolerance milling gives this flat stock tight dimensional control: thickness and squareness are held to plus or minus 0.001 inches, width tolerance is plus 0.000 to 0.005 inches, and length tolerance is plus 0.625 inches. It is supplied as a single piece per package.

This flat stock is suited for machine shops, fabrication facilities, and maintenance shops where raw stock must meet predictable dimensional tolerances before cutting, drilling, or welding. The C1018 grade machines cleanly and welds without special preheat under most shop conditions, making it a standard choice for jigs, fixtures, brackets, shafts, and general structural components in both light industrial and commercial settings. Metalworking professionals and millwrights are the typical end users for this type of raw material.

Designed as a standard AISI C1018 low carbon steel flat bar for general fabrication, machining, and structural applications where cold-rolled or turned flat stock of this grade and size is specified.

Installation Notes

Cutting, drilling, or welding this flat stock should be performed by qualified metalworkers or machinists using appropriate personal protective equipment and tooling rated for steel. Secure the workpiece in a vise or fixture before machining to maintain dimensional accuracy. When welding, follow applicable AWS guidelines and ensure adequate ventilation. Edges and cut ends may be sharp — deburr before handling or assembly.
