Starrett 54919 Low Carbon Steel Flat Stock C1018

Product Description

The STARRETT 54919 is a low carbon steel flat stock bar cut to 24 inches long, 6 inches wide, and 5/32 inch thick. Manufactured to AISI Type C1018 specification, this flat stock delivers consistent machinability and weldability suited to fabrication, maintenance, and repair work. Tolerances are tightly held: length runs plus 0.625 inches, width holds plus 0.000 to 0.005 inches, and both thickness and square tolerance are held to plus or minus 0.001 inches. At 6.38 pounds per piece, it is sized for bench work, in-shop fabrication, and field repair tasks performed by machinists, millwrights, pipefitters, and general tradespeople.

AISI C1018 low carbon steel flat stock is a standard choice for brackets, straps, spacers, shims, and structural supports in light to medium fabrication. Its low carbon content makes it well suited to welding, drilling, tapping, and bending without the need for pre-heat in most shop conditions. This piece is commonly used in HVAC equipment mounting, plumbing support fabrication, electrical panel framing, and general mechanical assembly where a reliable, machinable mild steel bar is required.

Installation Notes

Cut, drill, tap, or weld using tools and procedures appropriate for AISI C1018 mild steel. Wear appropriate PPE including eye protection and gloves when cutting or grinding. Deburr all cut edges before installation to avoid injury and to ensure proper fit against mating surfaces. Follow applicable shop safety and building code requirements for structural or load-bearing uses.
