Cold Rolled Steel C1144

Grade Summary:  Grade C1144 (also known as Stressproof® )is a medium carbon-free machining steel severely cold reduced to improve mechanical properties. Its inherent strength without heat treatment is comparable to heat treated steels of equal hardness.  It is specially treated to relieve the stress created by the cold drawing, thereby minimizing the warpage after machining which is common in ordinary cold drawn bars. Stressproof ® is a registered trademark of the LaSalle Steel Co.

Typical Applications:  Arbors, keyed shafts, spindles, gears, pinions, piston rods, sleeves, lead screws, racks, motor shafts, pump shafts, link pins, mandrels, boring bars, collets, bushings, drive shafts, armature shafts, king pins.

Available products: Round Bar and Ground Shaft
