Starrett 55009 Low Carbon Steel Flat Stock 24x3.5x0.625 in

Product Description

The STARRETT 55009 is a low carbon steel flat stock bar conforming to AISI Type C1018 material specification. This flat stock is cut to a nominal 24 x 3.5 x 0.625 inch profile and is intended for fabrication, machining, maintenance, and repair applications across mechanical, HVAC, plumbing, and general trade work. At 14.88 pounds per piece, this is a solid, machinable bar stock suited for brackets, supports, straps, and custom-fabricated components. Thickness tolerance is held to plus or minus 0.001 inches, making it appropriate where consistent cross-section is required for finished or semi-finished parts.

This flat stock bar is used in light to medium fabrication environments including residential and commercial HVAC equipment mounting, mechanical room support structures, plumbing hangers, and general repair tasks. It is also commonly cut down for custom brackets, wear plates, and alignment shims in trade installations. The C1018 low carbon steel composition provides good weldability and machinability, making it a practical choice for field fabrication or shop work where precision tolerancing matters.
