Starrett 54941 Low Carbon Steel Flat Stock C1018

Product Description

The STARRETT 54941 is a low carbon steel flat bar cut from AISI Type C1018 material, a general-purpose mild steel widely used in fabrication, machining, and structural applications. The bar measures 24 inches in length, 2.5 inches in width, and 0.25 inches in thickness, with a finished weight of 4.24 pounds. Tolerances are tightly held: length runs plus 0.625 inches, width holds plus 0.000 to 0.005 inches, and both thickness and squareness are controlled to plus or minus 0.001 inches. Machinists, fabricators, and maintenance technicians reach for this grade when they need a weldable, machinable stock that responds well to turning, drilling, and grinding without the complications of higher-alloy material.

C1018 flat stock serves a broad range of light industrial and trade applications. It is commonly used for brackets, plates, shims, keys, and structural supports in HVAC equipment rooms, mechanical rooms, and general construction. The flat bar format suits applications where a ready-to-use section is needed without additional milling. This piece is suited for both one-off repairs and small production runs where dimensional consistency matters.

Installation Notes

Cutting and shaping should be performed with tools rated for mild steel. Wear appropriate PPE including eye protection and gloves when cutting, grinding, or welding. Deburr all cut edges before installation to prevent injury and ensure proper mating surfaces. Follow applicable structural and mechanical codes for your jurisdiction when using flat stock in load-bearing or structural roles.
