Starrett 54971 Low Carbon Steel Flat Stock C1018

Product Description

The STARRETT 54971 is a low carbon steel flat stock bar measuring 24 inches long, 2.5 inches wide, and 0.375 inches thick. Manufactured to AISI Type C1018 specification, this flat stock offers 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. Weighing 6.38 pounds, it is suited for precision fabrication, tooling, and general machining applications where reliable material composition and dimensional consistency are required. Machinists, fabricators, and industrial tradespeople work with this stock in both shop and field settings.

This flat stock is commonly used in machine shops, maintenance and repair operations, and light fabrication environments. It is appropriate for applications requiring a machinable, weldable low carbon steel with predictable mechanical behavior. Typical uses include fixtures, brackets, gussets, and custom tooling components. The controlled tolerances make it a dependable choice when dimensional accuracy matters from the start of a project.

Installation Notes

Cutting, drilling, and machining should be performed by qualified machinists or fabricators using appropriate tooling for low carbon steel. Wear appropriate personal protective equipment when cutting or grinding. Edges may be sharp as received — deburr before handling or fitting into assemblies. Store flat to prevent warping or bending during storage.
