Starrett 54985 Steel Flat Stock 24x1x0.5 in Aisi C1018

Product Description

The STARRETT 54985 is a low carbon steel flat stock bar measuring 24 inches long, 1 inch wide, and 0.5 inches thick, manufactured to AISI Type C1018 material specification. This bar stock is intended for fabrication, machining, maintenance, and repair applications where mild steel with predictable tolerances is required. Tight dimensional control is built in: thickness and square tolerance held to plus or minus 0.001 inches, width tolerance held to plus 0.000 to 0.005 inches, and length tolerance held to plus 0.625 inches. At 3.4 pounds, it ships as a single piece and is ready for bench or machine work directly from the package.

AISI C1018 low carbon steel flat bar is a common choice in general fabrication shops, maintenance departments, and metalworking trades. Typical uses include brackets, spacers, shims, guides, reinforcement plates, and custom tooling components. The 0.5-inch thickness provides enough cross-section for moderate structural and mechanical applications without requiring heavy-duty cutting equipment. Machinists, millwrights, welders, and general fabricators regularly work with this form and size for both one-off parts and short production runs.

Key Features

• AISI Type C1018 low carbon steel for consistent machinability and weldability

• Length tolerance of plus 0.625 inches allows for cut-to-length finishing
• Single-piece packaging with a minimum order quantity of 1
• 3.4 pound weight suits bench handling without lifting equipment

Compatibility

Designed as a general-purpose flat bar stock suitable for fabrication, repair, and maintenance applications requiring AISI C1018 low carbon mild steel in a 24 x 1 x 0.5 inch form factor.

Installation Notes

Cutting, drilling, and welding of C1018 flat stock should be performed by qualified fabricators or machinists using appropriate personal protective equipment. Deburr all cut edges before handling or fitting into assemblies. If welding, follow standard procedures for low carbon mild steel and allow parts to cool before final dimensioning. Store flat on a clean surface to prevent bowing or surface contamination prior to use.
