Starrett 54930 Low Carbon Steel Flat Stock 3/16x4x24 in

Product Description

The STARRETT 54930 is a low carbon steel flat stock bar measuring 3/16 inch thick by 4 inches wide by 24 inches long, manufactured to AISI Type C1018 material specification. This mill-finish flat bar is used in fabrication, maintenance, and repair applications where a weldable, machinable low carbon steel stock is required. Thickness and squareness are held to a tolerance of plus or minus 0.001 inches, and width tolerance runs plus 0.000 to 0.005 inches, making it suitable for layout work and precision fit-up. Weight is 5.1 pounds per piece. Machinists, fabricators, millwrights, and maintenance technicians are the typical end users.

This flat stock is suited for general industrial and commercial fabrication tasks including brackets, supports, spacers, shims, and structural repair stock. The C1018 specification indicates a low carbon content that supports welding with standard MIG or stick processes and responds well to drilling, tapping, and grinding without special tooling. At 24 inches in length and 4 inches wide, this piece is practical for bench work and short-run fabrication without the need to cut down larger stock.
