Starrett 55024 Low Carbon Steel Flat Stock Aisi C1018

Product Description

The STARRETT 55024 is a low carbon steel flat stock bar made to AISI Type C1018 material specification. It measures 24 inches in length, 3-1/2 inches in width, and 3/4 inch in thickness, with a weight of 17.86 pounds. This bar stock is machined or cut to close tolerances, making it suitable for layout work, toolmaking, fixturing, and general fabrication tasks where consistent dimensions and flatness are required. The C1018 designation indicates a mild, low carbon steel that machines and welds cleanly. Machinists, tool and die workers, and fabricators working in job shops, maintenance departments, and manufacturing facilities are the primary users of this material.

This flat bar is used in a wide range of industrial and trade applications including fixture bases, gib stock, spacers, shims, and machine components. Its close width and thickness tolerances make it well suited for applications where dimensional consistency directly affects fit and function. The 24-inch length provides workable stock for bench-level machining, grinding, or cutting to final dimension. Both hobbyist machinists and professional tradespeople working with manual or CNC equipment will find this stock ready to use with minimal preparation.

Installation Notes

Cutting, drilling, or grinding of this flat stock should be performed with appropriate personal protective equipment including eye protection and gloves. Secure the bar in a vise or fixture before machining to prevent movement. Deburr all cut edges before handling or assembling into finished components. Follow applicable shop safety standards and equipment manufacturer guidelines when processing steel bar stock.
