Starrett 55028 Low Carbon Steel Flat Stock Aisi C1018

Product Description

The STARRETT 55028 is a low carbon steel flat stock bar measuring 24 inches long, 8 inches wide, and 0.75 inches thick. Manufactured to AISI Type C1018 specification, this flat stock delivers consistent machinability and weldability suited to a wide range of fabrication and maintenance applications. Dimensional tolerances are tightly held: length tolerance is plus 0.625 inches, width tolerance is plus 0.000 to 0.005 inches, and both thickness and squareness tolerances are held to plus or minus 0.001 inches. At 40.6 pounds per piece, this is a substantial bar intended for structural, repair, and custom fabrication work performed by skilled tradespeople and machinists.

This flat stock is commonly used in HVAC equipment fabrication, plumbing and mechanical support structures, electrical panel framing, and general industrial maintenance. It is appropriate for applications requiring a reliable, cold-finished or hot-rolled low carbon steel bar where precise thickness and squareness are critical. Shops, field fabricators, and maintenance technicians use this material to fabricate brackets, supports, wear plates, and structural reinforcements. Its low carbon content makes it readily weldable and suitable for light forming operations without requiring preheat in most shop conditions.

Compatibility

Designed as a general-purpose flat stock bar for use in fabrication, repair, and structural support applications across mechanical, HVAC, plumbing, and industrial trades wherever AISI C1018 low carbon steel flat bar stock is specified.

Installation Notes

This material is typically cut, drilled, welded, or machined by qualified tradespeople or machinists using appropriate metalworking tools. Wear proper PPE including eye protection and gloves when cutting or grinding. Follow applicable shop safety standards and local codes when incorporating steel stock into structural or mechanical assemblies. Verify final dimensions after any cutting operation, as stock is supplied with tolerance allowance on length.
