Starrett 55063 Low Carbon Steel Flat Stock C1018

Product Description

The STARRETT 55063 is a low carbon steel flat stock bar measuring 24 inches long, 8 inches wide, and 1-1/4 inches thick, manufactured to AISI Type C1018 material specification. Weighing approximately 68 pounds, this flat stock is suited for machining, fabrication, and general metalworking applications where close dimensional tolerances are required. Thickness and square tolerances are held to plus or minus 0.001 inches, width tolerance runs plus 0.000 to 0.005 inches, and length tolerance is plus 0.625 inches. Machinists, fabricators, and maintenance welders working in shops, manufacturing facilities, or on-site metalwork use this bar as raw stock for brackets, plates, fixtures, and structural components.

This flat bar is appropriate for general-purpose industrial and commercial fabrication. Its C1018 low carbon chemistry makes it readily machinable and weldable without requiring special preheat procedures in most applications. The consistent dimensional tolerances support accurate layout and machining work, reducing secondary dressing operations. Typical uses include structural supports, mounting plates, spacers, and custom parts cut to length in the field or shop environment.

Installation Notes

Handling and cutting of this flat stock should be performed by qualified machinists or fabricators using appropriate material handling equipment given the 68-pound weight. Standard metal cutting tools, band saws, or milling equipment are typically used to cut and shape flat stock bars. Follow applicable shop safety standards and wear appropriate PPE including eye protection and gloves when cutting or grinding. Secure the workpiece firmly before any machining or cutting operation to prevent movement.
