Starrett 54929 C1018 Steel Flat Stock 3/16x3.5x24 in

Product Description

The STARRETT 54929 is a low carbon steel flat bar cut from AISI Type C1018 material, a general-purpose mild steel known for consistent machinability and weldability. The bar measures 24 inches long, 3-1/2 inches wide, and 3/16 inch thick, weighing 4.46 pounds per piece. Tolerances are tightly held: length at plus 0.625 inches, width at plus 0.000 to 0.005 inches, and both thickness and squareness at plus or minus 0.001 inches. This stock is suited for fabrication, repair, and custom part layout work performed by machinists, millwrights, welders, and maintenance trades.

C1018 flat bar in this size range is commonly used in light structural fabrication, fixture building, brackets, straps, and general metalworking applications. The 3/16-inch thickness makes it easy to cut, drill, tap, and weld without heavy tooling. It is a standard mill-finish bar appropriate for shop environments where close dimensional tolerances are required before secondary machining or finishing operations.

Installation Notes

Cutting, drilling, and welding of C1018 flat bar should be performed by qualified machinists or fabricators using appropriate personal protective equipment. Deburr all cut edges before handling or fitting parts. When welding, follow applicable AWS guidelines for low carbon mild steel. Store flat bar horizontally on supported racks to prevent warping or bowing over time.
