Starrett 54940 Low Carbon Steel Flat Stock 0.25x2x24 in

Product Description

The STARRETT 54940 is a low carbon steel flat stock bar cut to 24 inches long, 2 inches wide, and 0.25 inches thick. Manufactured to AISI Type C1018 specification, this mild steel flat bar offers reliable machinability and weldability for a wide range of fabrication tasks. Tolerances are held tight: length is cut to a plus 0.625 inch tolerance, width to a plus 0.000 to 0.005 inch tolerance, and both thickness and squareness to plus or minus 0.001 inch. Machinists, fabricators, millwrights, and maintenance technicians reach for C1018 flat stock when a readily available, consistently dimensioned mild steel bar is needed for structural, mechanical, or repair applications.

This flat stock is suited for general industrial and commercial fabrication work. It is commonly used in machine shops, maintenance and repair operations, and light structural applications where precise dimensions matter. The 24 x 2 x 0.25 inch profile makes it a practical starting blank for brackets, keys, shims, support plates, and similar components. The tight thickness and squareness tolerances reduce secondary finishing time when close-fit parts are required.

Key Features

• AISI C1018 low carbon steel for good machinability and weldability
• Thickness and square tolerance held to plus or minus 0.001 inch
• Width tolerance of plus 0.000 to 0.005 inch for consistent fit
• Length tolerance of plus 0.625 inch allows for facing to final dimension
• Uniform 0.25 x 2 inch cross-section for predictable material removal

Compatibility

Designed as a general-purpose C1018 low carbon steel flat bar suitable for machine shop, fabrication, and MRO applications requiring a standard mild steel flat stock profile.

Installation Notes

Cutting, drilling, and welding of C1018 steel flat stock should be performed by qualified machinists or fabricators using appropriate tooling and personal protective equipment. Deburr all cut edges before fitting into assemblies. When welding, follow standard procedures for low carbon steel and allow the workpiece to cool appropriately before handling. Consult applicable facility safety and applicable codes when incorporating structural steel components into building or equipment frames.
