Starrett 54942 Low Carbon Steel Flat Stock 24x3x0.25 in

Product Description

The STARRETT 54942 is a low carbon steel flat bar cut to 24 x 3 x 0.25 inches, conforming to AISI Type C1018 material specification. It is a general-purpose steel stock used in fabrication, maintenance, and repair applications across mechanical, HVAC, plumbing, and structural trades. The piece weighs 5.1 pounds and holds tight dimensional tolerances: plus or minus 0.001 inches on thickness and squareness, a width tolerance of plus 0.000 to 0.005 inches, and a length tolerance of plus 0.625 inches. These tolerances make it suitable where dimensional consistency is required for brackets, supports, straps, and custom-fabricated components.

This flat stock is appropriate for light fabrication work in residential and commercial settings. Common applications include custom equipment mounting brackets, ductwork supports, pipe hangers, and structural reinforcements where a machinable, weldable low carbon steel is specified. C1018 is known for its good weldability and machinability, making it a practical choice for field-fabricated parts and shop work. It ships as a single piece at the stated dimensions with no further processing required.

Installation Notes

This material is typically cut, drilled, welded, or formed by sheet metal workers, pipefitters, HVAC technicians, or general fabricators using standard hand and power tools. When welding, follow applicable AWS guidelines and ensure adequate ventilation. Wear appropriate PPE including gloves and eye protection when cutting or grinding. Deburr all cut edges before installation in any assembly.
