Starrett 57255 Low Carbon Steel Flat Stock C1018

Product Description

The STARRETT 57255 is a low carbon steel flat bar stock cut to 24 x 3.5 x 0.875 inches and manufactured to AISI Type C1018 material specification. C1018 is a mild, low carbon steel widely used in general fabrication, machining, and structural applications where moderate strength and excellent weldability are required. The stock ships at 20.82 pounds and holds tight dimensional tolerances: plus 0.625 inches on length, plus 0.000 to 0.005 inches on width, and plus or minus 0.001 inches on both thickness and squareness. These controlled tolerances make it suitable for layout work, tool and fixture building, and precision flat stock applications.

C1018 flat bar is a standard shop-floor material used by machinists, fabricators, millwrights, and maintenance technicians in both light industrial and commercial settings. It is commonly used for brackets, keys, shims, fixtures, spacers, and support plates. The consistent cross-section and close width and thickness tolerances reduce secondary machining time when dimensional accuracy matters at the start of a job. This piece is sold individually as a single-length bar.
