Starrett 54996 Low Carbon Steel Flat Stock C1018

Product Description

The STARRETT 54996 is a low carbon steel flat stock bar cut to 24 inches long, 8 inches wide, and 0.5 inches thick. Manufactured to AISI Type C1018 specification, this flat stock delivers consistent machinability and weldability suited to fabrication, maintenance, and repair applications. Tolerances are held tight across all three axes: thickness and square tolerance are held to plus or minus 0.001 inches, width tolerance runs plus 0.000 to 0.005 inches, and length tolerance allows a plus 0.625 inch overage. At 27.2 pounds per piece, this is a solid, production-grade bar ready for layout work, fixture building, or general structural fabrication.

This flat stock is used across metalworking, industrial maintenance, and light fabrication shops. It suits applications where a reliable, machinable mild steel is needed for brackets, plates, shims, tooling fixtures, and repair stock. The C1018 grade responds well to drilling, milling, turning, and welding without requiring specialized tooling or preheat procedures under most shop conditions. It is handled by machinists, millwrights, maintenance technicians, and fabricators in both commercial and industrial settings.

Compatibility

Designed as a general-purpose AISI C1018 low carbon steel flat bar for machining, fabrication, and maintenance repair operations where mild steel flat stock in 0.5 x 8 x 24 inch dimensions is required.

Installation Notes

Flat stock of this size and weight requires appropriate material handling equipment during positioning and fixturing. Machinists and fabricators should de-burr cut edges before final assembly or handling. Follow applicable shop safety practices and OSHA material handling guidelines when moving or securing pieces of this weight. Welding this C1018 grade follows standard mild steel procedures — consult AWS D1.1 or applicable structural welding codes for joint design requirements.
