Starrett 55058 Low Carbon Steel Flat Stock Aisi C1018

Product Description

The STARRETT 55058 is a low carbon steel flat stock bar measuring 24 inches long, 2.5 inches wide, and 1.25 inches thick. Manufactured to AISI Type C1018 specification, this flat stock delivers consistent dimensional accuracy with tightly controlled tolerances: plus or minus 0.001 inches on thickness and squareness, plus 0.000 to 0.005 inches on width, and plus 0.625 inches on length. C1018 low carbon steel offers good machinability and weldability, making it a dependable raw material for fabrication, machining, and general metalworking applications. The bar ships as a single piece at approximately 21.26 pounds.

This flat stock is suited for use in machine shops, fabrication facilities, and maintenance environments where a reliable, machinable steel bar is needed. Typical applications include fixture components, spacers, brackets, bases, and structural supports. The C1018 grade responds well to drilling, milling, turning, and welding without requiring specialized tooling or pre-heat procedures in most shop conditions. It is appropriate for both light structural and precision-fit fabrication work.
