Carbon Steel 1018 Product Guide Product   | Carbon Steel 1018 Square Bar Tolerances product

Carbon Steel Square 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 square bar stock is available in full size and custom cut lengths.

 

We also carry 1018 rectangle bar in Precision Ground
