Starrett 54917 Low Carbon Steel Flat Stock C1018

Product Description

The STARRETT 54917 is a low carbon steel flat stock bar made to AISI Type C1018 material specification. It measures 5/32 inch thick, 4 inches wide, and 24 inches long, and weighs 4.25 pounds. C1018 is a mild, low carbon steel known for good machinability, weldability, and consistent mechanical properties, making it a reliable choice for general fabrication work. Tolerances are tightly controlled: thickness and square tolerance are both plus or minus 0.001 inch, width tolerance is plus 0.000 to 0.005 inch, and length tolerance is plus 0.625 inch. This bar is sold as a single piece and is suited for shop fabrication, layout work, and light structural applications.

This flat stock is appropriate for machine shops, metal fabricators, maintenance facilities, and tradework requiring a precision-tolerance mild steel bar. It works well as raw stock for brackets, spacers, shims, mounting plates, and similar components. The 24-inch length and 4-inch width give a workable blank for a wide range of cut-to-fit applications. Electricians, HVAC fabricators, pipefitters, and general contractors who perform in-shop fabrication will find this bar suitable for routine metalwork tasks.

Compatibility

Designed as a general-purpose flat bar for fabrication applications requiring AISI C1018 low carbon steel stock in a 5/32 x 4 x 24 inch form factor.

Installation Notes

Cutting, drilling, and welding of C1018 steel should be performed by qualified fabricators using appropriate personal protective equipment and ventilation. Deburr all cut edges before handling or installation. When welding, follow applicable AWS or shop welding procedures for low carbon steel. Ensure workpieces are secured properly before machining operations to maintain dimensional tolerances.
