1144 A-311 Cold Drawn Steel Bar
1144 cold drawn steel bar is a carbon-manganese grade produced using a proprietary process that draws the bar through a special die under heavy draft. It is then stress relieved in a precisely controlled furnace. The grade is beneficial since it is stress relieved and annealed. It provides improved wearability without case hardening, strength without heat treating and excellent machinability. Eaton stocks a number of diameters of this grade to meet your demands quickly.
