Starrett 54936 Low Carbon Steel Flat Stock Aisi C1018

Product Description

The STARRETT 54936 is a low carbon steel flat stock bar made to AISI Type C1018 material specification. It measures 24 inches long, 0.75 inches wide, and 0.25 inches thick, and weighs 1.27 pounds. C1018 is a general-purpose mild steel known for good machinability, weldability, and consistent mechanical properties. This flat stock ships as a single piece and is suited for fabrication, maintenance, and repair work where close dimensional tolerances are required. Thickness and squareness tolerances are held to plus or minus 0.001 inches, and width tolerance is controlled to a plus 0.000 to 0.005 inch range, making it appropriate for precision layout and structural fabrication tasks.

This flat stock is used across industrial, mechanical, and trade applications including HVAC equipment frames, brackets, support channels, and field-fabricated mounting hardware. Plumbers, pipefitters, and general contractors also use C1018 flat bar for custom supports, straps, and anchoring components. The 24-inch length is a standard cut suitable for bench work and on-site fabrication without requiring additional saw cuts in most applications.

Installation Notes

Cutting, drilling, and welding of C1018 flat stock should be performed by qualified tradespeople using appropriate personal protective equipment and ventilation. Deburr all cut edges before installation to prevent injury and ensure proper fit against mating surfaces. When welding or grinding indoors, follow applicable OSHA and local safety codes for fume control. Power down any adjacent electrical or mechanical equipment before installing fabricated components in live systems.
