Starrett 57256 Low Carbon Steel Flat Stock C1018

Product Description

The STARRETT 57256 is a low carbon steel flat stock bar measuring 1 inch thick, 7 inches wide, and 24 inches long, manufactured to AISI Type C1018 material specification. This cold-finished flat stock delivers consistent dimensional accuracy with tight tolerances: plus or minus 0.001 inch on thickness and square, plus 0.000 to 0.005 inch on width, and plus 0.625 inch on length. At 47.6 pounds, it is a solid, full-section bar suited for fabrication, fixture building, tooling bases, and structural components where precise material dimensions are required. Machinists, fabricators, and maintenance professionals working in industrial and trade settings use this bar for a wide range of flat-material applications.

This flat stock is appropriate for general-purpose fabrication tasks including brackets, mounting plates, wear plates, shims, and support structures. Its C1018 low carbon composition offers good machinability and weldability, making it a common choice in job shop environments, maintenance departments, and industrial fabrication facilities. The 1-inch thickness provides substantial cross-section for load-bearing or structural use, while the 7-inch width reduces the need for additional material joining in wider part applications.

Installation Notes

Cutting, drilling, and machining should be performed by qualified machinists or fabricators using tooling rated for low carbon steel. Always wear appropriate PPE including eye protection and gloves when cutting or grinding steel flat stock. Secure the bar properly in a vise or fixture before any machining or cutting operation to prevent movement. Verify final cut dimensions against drawing tolerances before use in precision assemblies.
