Starrett 54945 Low Carbon Steel Flat Stock C1018

Product Description

The STARRETT 54945 is a low carbon steel flat bar cut to 24 x 5 x 0.25 inches and conforming to AISI Type C1018 material specification. It is a general-purpose flat stock used in fabrication, maintenance, and mechanical applications across the trades. The piece weighs 8.5 pounds and ships as a single unit. Thickness and square tolerances are held to plus or minus 0.001 inches, and width tolerance is controlled at plus 0.000 to 0.005 inches, making this stock suitable where dimensional consistency matters. HVAC sheet metal shops, plumbing contractors, and general fabricators routinely use flat stock of this type for brackets, supports, and repair components.

This flat stock is sized for bench work and light structural fabrication in both residential and commercial settings. The 24-inch length is convenient for cutting to finish dimensions on a band saw or cold saw. C1018 is a mild, low carbon steel grade known for good machinability and weldability, making it a common choice when a part will be drilled, tapped, welded, or bent to shape on site or in a shop. The 5-inch width provides adequate material for most bracket and strap applications without requiring additional processing to reduce width.

Installation Notes

Cutting, drilling, or welding of steel flat stock should be performed by qualified tradespeople using appropriate personal protective equipment including eye and hand protection. Deburr all cut edges before handling or assembly. When welding C1018 steel, follow applicable AWS procedures and ensure adequate ventilation. Secure the workpiece properly before any machining operation to prevent movement.
