Starrett 55022 Low Carbon Steel Flat Stock C1018

Product Description

The STARRETT 55022 is a low carbon steel flat bar cut to 24 inches in length, 2.5 inches wide, and 0.75 inches thick. It is produced to AISI Type C1018 material specification, a mild steel grade known for consistent machinability and weldability. Weighing 12.76 pounds per piece, this flat stock is suited for fabrication, tooling fixtures, machine bases, and structural support work. Tolerances are tightly controlled: length runs plus 0.625 inches, width holds plus 0.000 to 0.005 inches, and both thickness and squareness are held to plus or minus 0.001 inches. Machinists, fabricators, and tool-and-die professionals rely on this material where dimensional consistency and close tolerances are required.

This flat stock is appropriate for general metalworking and industrial fabrication applications in both shop and field environments. Typical uses include jig and fixture construction, weld-on brackets, keystock blanks, spacers, and structural tie bars. The 24-inch length suits bench-work and light structural tasks without requiring further saw cutting in most applications. The C1018 grade machines cleanly with standard HSS or carbide tooling and accepts MIG, TIG, and stick welding processes without special preheat under most shop conditions.

Installation Notes

Cutting, drilling, and welding operations should be performed by qualified metalworkers or machinists following applicable shop safety practices. Secure the workpiece fully before cutting or machining to prevent movement. Deburr all cut edges before assembly or handling. Follow applicable OSHA and facility safety codes when operating saws, mills, or welding equipment on this material.
