Starrett 54997 Steel Flat Stock 1/2x9x24 in Aisi C1018

Product Description

The STARRETT 54997 is a low carbon steel flat stock bar made to AISI Type C1018 material specification. It measures 24 inches long, 9 inches wide, and 0.5 inches thick, and weighs 30.6 pounds. C1018 is a widely used mild steel grade valued for its consistent machinability, weldability, and surface finish response, making it a dependable choice for fabrication, repair, and custom part work. Tolerances are held tight: length at plus 0.625 inches, width at plus 0.000 to 0.005 inches, and thickness and squareness each at plus or minus 0.001 inches. Machinists, fabricators, welders, and maintenance trades use this stock as raw material for brackets, wear plates, shims, and structural components.

This flat stock suits a broad range of light fabrication and repair applications in industrial, commercial, and trade service environments. Its 9 by 24 inch footprint and half-inch thickness make it practical for cutting down into smaller parts or using as a full plate in jig and fixture work. The C1018 grade machines cleanly on mills and lathes, accepts MIG and TIG welding without special preheat under most conditions, and can be case-hardened when surface wear resistance is needed. It is sold as a single piece per package with a minimum order quantity of one.
