Starrett 55048 Low Carbon Steel Flat Stock C1018

Product Description

The STARRETT 55048 is a low carbon steel flat bar cut to 24 inches long, 4 inches wide, and 1 inch thick. Manufactured to AISI Type C1018 specification, this flat stock delivers consistent machinability and weldability suited to a wide range of fabrication, repair, and tooling applications. Dimensional tolerances are held tight: length is cut to a plus 0.625 inch tolerance, width holds plus 0.000 to 0.005 inch, and both thickness and square are controlled to plus or minus 0.001 inch. At 27.2 pounds per piece, this is a solid, single-piece bar intended for bench stock, structural builds, or precision layout work.

This flat stock is well suited to machine shops, maintenance and repair operations, and general fabrication environments. It is commonly used as raw material for brackets, plates, fixtures, spacers, and wear components. The C1018 grade is a standard low-carbon steel that responds well to drilling, milling, turning, and welding, making it a practical choice wherever hot-rolled or cold-drawn bar stock is specified. Trade professionals sourcing cut-to-size flat bar for in-shop or field fabrication will find this piece ready for immediate use.

Installation Notes

Cutting, grinding, drilling, or welding this flat stock should be performed by qualified machinists or fabricators using appropriate personal protective equipment. Secure the bar firmly in a vise or fixture before machining to prevent movement. Follow applicable shop safety standards and local codes when welding or thermally cutting carbon steel. Inspect cut surfaces and verify final dimensions before fitting into any structural or load-bearing assembly.
