Starrett 55059 Low Carbon Steel Flat Stock 24x3x1.25 in

Product Description

The STARRETT 55059 is a low carbon steel flat stock bar cut to 24 inches long, 3 inches wide, and 1.25 inches thick. It conforms to AISI Type C1018 material specification, a standard low carbon steel known for its machinability, weldability, and consistent mechanical properties. This flat bar is precision-ground to tight tolerances: plus or minus 0.001 inches on thickness and square, plus 0.000 to 0.005 inches on width, and plus 0.625 inches on length. At 25.5 pounds, this is a solid, full-section bar suited for fabrication, tooling, and general metalworking applications. Machinists, tool and die makers, and maintenance tradespeople are the primary installers and users of this stock.

This flat stock is used in job shops, maintenance departments, and fabrication facilities where precise, ready-to-machine steel bar stock is required. Common applications include fixture bases, wear plates, keys, spacers, shims, brackets, and general structural components. The C1018 grade machines cleanly and accepts welds without special preheat in most shop conditions, making it a practical choice for both prototype and production work in light to medium industrial settings.

Installation Notes

Cutting, drilling, milling, and welding of this flat stock should be performed by qualified machinists or metalworkers using appropriate tooling and personal protective equipment. Secure the bar firmly in a vise or fixture before any machining operation to prevent movement. When welding, follow standard shop procedures for low carbon steel. Consult applicable facility safety codes before cutting or grinding operations.
