1144 Cold Drawn Steel Bar

Cold drawn 1144 steel bar is a medium carbon steel that contains high manganese and sulfur. In the cold drawn form, this grade exhibits high tensile properties. Because of the high strength, it can often be used without requiring any heat treatments. This grade is also considered free machining and has good wear resistance compared to other cold drawn grades. Eaton Steel Bar Company stocks several diameters of 1144 steel bar to meet your demands quickly. We also supply 1144 cold drawn bar to various industries like aerospace, automotive, and more.
