Starrett 54931 Low Carbon Steel Flat Stock 3/16x5x24 in

Product Description

The STARRETT 54931 is a low carbon steel flat stock bar cut to 24 inches long, 5 inches wide, and 3/16 inch thick. It is manufactured to AISI Type C1018 specification, a mild steel grade widely used in fabrication, machining, and structural applications where high strength is not required but consistent machinability and weldability are. At 6.38 pounds per piece, this flat bar is sized for bench work, brackets, frame members, and general metalworking tasks. Machinists, fabricators, and maintenance trades stock this material for custom part fabrication and repair work.

This flat stock is suited for light structural, mechanical, and fabrication applications in both shop and field environments. C1018 low carbon steel machines cleanly, accepts welding without special preheat requirements in most cases, and can be drilled, tapped, and formed with standard tooling. It is a common choice for support brackets, gussets, wear plates, shims, and custom mechanical components across industrial, commercial, and maintenance applications.

Compatibility

Designed as a general-purpose flat bar for fabrication and machining applications requiring AISI C1018 low carbon steel in a 3/16 x 5 x 24 inch form factor.

Installation Notes

Cutting, drilling, and welding of steel flat stock should be performed by qualified fabricators or machinists following applicable shop safety procedures. Use appropriate personal protective equipment including eye protection and gloves when cutting or grinding. Secure the workpiece firmly before machining operations. Verify final dimensions after cutting, as length tolerance allows for stock overage that must be trimmed to final spec.
