Starrett 54979 Low Carbon Steel Flat Stock Aisi C1018

Product Description

The STARRETT 54979 is a low carbon steel flat stock bar made to AISI Type C1018 material specification. It measures 24 inches long, 9 inches wide, and 0.375 inches thick, and weighs 22.96 pounds. C1018 is a general-purpose mild steel known for consistent machinability, weldability, and moderate strength, making it a reliable choice for fabrication, tooling fixtures, mounting plates, and structural supports. Machinists, fabricators, and maintenance technicians use flat stock like this as raw material for custom parts or as a ready-cut blank that requires minimal stock removal before final dimensions are achieved.

This flat stock is suited for light industrial and commercial fabrication applications where close dimensional control is needed. The tight thickness and square tolerances make it appropriate for use in jigs, fixtures, brackets, shims, and general metalworking projects. It is commonly found in machine shops, maintenance departments, and fabrication facilities that require cut-to-size mild steel in a manageable flat bar format. The piece ships as a single unit and is sold individually.
