Starrett 54964 Low Carbon Steel Flat Stock C1018

Product Description

The STARRETT 54964 is a low carbon steel flat stock bar made to AISI Type C1018 material specification. It measures 24 inches in length with a 0.375 inch thickness and 0.375 inch width. C1018 is a general-purpose mild steel with good machinability and weldability, commonly used in fabrication, tooling fixtures, and maintenance applications. The stock ships in a single piece per package and is held to tight dimensional tolerances, making it suitable for precision layout work, shim stock, or machined component blanks. Licensed machinists, fabricators, and millwrights are the primary installers and users of this material.

This flat stock is used in industrial, commercial, and light manufacturing settings where a close-tolerance, low carbon steel bar is needed for stock removal, welding buildup, fixture construction, or repair work. The 24 inch length accommodates common bench and machine setups without requiring initial cuts. The square cross-section profile simplifies fixturing and clamping during machining operations.

Installation Notes

Cutting, drilling, or welding this material should be performed by a qualified machinist or fabricator using appropriate tooling for mild steel. Always de-burr cut edges before handling or fitment to avoid injury. Follow applicable shop safety standards and ensure all clamping and fixturing is secure before machining operations begin.
