Starrett 54939 Low Carbon Steel Flat Stock C1018

Product Description

The STARRETT 54939 is a low carbon steel flat stock bar cut to 24 inches in length, 1.5 inches wide, and 0.25 inches thick. It is made from AISI Type C1018 steel, a widely used low carbon grade valued for its machinability, weldability, and consistent mechanical properties. This flat stock is held to tight dimensional tolerances, making it suitable for fabrication, layout work, and precision fixturing tasks. It is commonly purchased by machinists, pipefitters, electricians, and general trade fabricators who need a known-grade steel bar for structural or custom component work.

This flat stock is appropriate for light to medium fabrication applications in both residential and commercial trade environments. Typical uses include shim stock, mounting brackets, strap fabrication, and support reinforcement in HVAC, plumbing, and electrical installations. The C1018 grade machines cleanly, accepts welding without significant difficulty, and can be drilled and tapped without special tooling. Each piece is supplied individually and is intended for direct use or further machining.

Installation Notes

Installation and use of this flat stock should be performed by qualified trade professionals familiar with metal fabrication practices. Wear appropriate personal protective equipment including eye protection and gloves when cutting, drilling, or grinding. Follow applicable local codes and standards for structural or load-bearing applications. Deburr all cut edges before installation to prevent injury and ensure proper fitment.
