Show full description
09-07-2025 - carbon steel bar-rectangle 1018 - 1000x1000superZoom-main

Carbon Steel Rectangle Bar 1018

Carbon Steel Rectangle/Flat Bar 1018 is normally used for machine, automotive, tool, and ornamental applications. 1018 steel is the most commonly available of the cold-rolled steels. It has a good combination of all of the typical traits of steel - strength, some ductility, and comparative ease of welding and machining. 1018 rectangle/flat bar stock is available in full size and custom cut lengths.

 

We also carry Metric 1018 rectangle bar.
