Starrett 54992 Low Carbon Steel Flat Stock Aisi C1018

Product Description

The STARRETT 54992 is a low carbon steel flat stock bar cut to 24 inches long, 4 inches wide, and 0.5 inches thick, conforming to AISI Type C1018 material specification. It is a cold-finished steel flat used in fabrication, maintenance, and repair applications across industrial and trade settings. At 13.6 pounds per piece, this bar ships as a single unit and is ready for layout, machining, welding, or structural fitment work. Tolerances are tightly held: thickness and square tolerance are held to plus or minus 0.001 inches, width tolerance runs plus 0.000 to 0.005 inches, and length tolerance is plus 0.625 inches.

This flat stock is suited for general fabrication shops, maintenance facilities, and job-site metalwork where a reliable, low carbon steel bar is needed in a manageable size. AISI C1018 is a standard low carbon steel with good weldability and machinability, making it appropriate for brackets, supports, frame components, and similar structural or utility parts. It is commonly used by fabricators, millwrights, pipefitters, and general maintenance tradespeople who need a known-spec steel bar without additional surface hardening.

Installation Notes

Handling and cutting of steel flat stock should be performed by qualified fabricators or tradespeople using appropriate metalworking tools such as band saws, angle grinders, or milling equipment. Wear proper PPE including gloves and eye protection when cutting or grinding. De-burr all cut edges before fitment. If welding, follow applicable AWS standards and ensure the work area is properly ventilated.
