Starrett 55073 Low Carbon Steel Flat Stock 24x6x1.5 in

Product Description

The STARRETT 55073 is a low carbon steel flat stock bar measuring 24 inches long, 6 inches wide, and 1.5 inches thick. Conforming to AISI Type C1018 material specification, this flat stock delivers consistent mechanical properties typical of low carbon steel, including good machinability and weldability. Tolerances are held tight across all dimensions: plus 0.625 inches on length, plus 0.000 to 0.005 inches on width, and plus or minus 0.001 inches on both thickness and squareness. At 61.2 pounds, this is a substantial piece suited for shop fabrication, tooling, fixturing, and general metalworking applications. Machinists, fabricators, and maintenance technicians are the primary users.

This flat stock is used in industrial and commercial fabrication environments where precise raw material dimensions are required before machining, cutting, or welding. Common applications include machine bases, fixture plates, die components, brackets, and structural support members. The C1018 specification makes it suitable for case hardening and light forming operations. It is appropriate for both job shop and in-house maintenance departments working with ferrous stock in standard mill sizes.

Compatibility

Designed as a standard AISI C1018 low carbon steel flat bar for general fabrication, machining, and metalworking use where mill-tolerance ferrous flat stock is required.

Installation Notes

Handling of this flat stock requires appropriate lifting equipment or a two-person lift given its 61.2-pound weight. Cutting, grinding, or machining operations should be performed with proper machine guarding, eye protection, and chip containment in place. Welding C1018 steel follows standard low carbon steel procedures and does not typically require preheat at this section thickness, though shop conditions and applicable codes should always be verified by the qualified tradesperson performing the work. Secure the workpiece firmly before any machining or cutting operation to prevent movement.
