Starrett 54938 Steel Flat Stock 24x1-1/4x1/4 in Aisi C1018

Product Description

The STARRETT 54938 is a low carbon steel flat stock bar cut to 24 x 1-1/4 x 1/4 inches and manufactured to AISI Type C1018 material specification. This flat stock is used as raw material for fabrication, repair work, and custom component manufacturing across mechanical, HVAC, plumbing, and general trades. The C1018 grade provides good machinability and weldability, making it suitable for bending, drilling, and light forming operations. Thickness and square tolerances are held to plus or minus 0.001 inches, with width tolerance of plus 0.000 to 0.005 inches and a length tolerance of plus 0.625 inches. Weight is 2.12 pounds per piece.

This flat bar is appropriate for use in residential and commercial trade applications where a close-tolerance, low carbon steel stock is needed. Typical uses include fabricating brackets, support tabs, strap hardware, and filler pieces during mechanical system installations or retrofits. The tight dimensional tolerances make it well suited for precision layout work or applications where consistent thickness is required across multiple pieces.
