C1144 Stressproof®:

Disclaimer: The content of this page is for general information only and is not to be used for engineering or design. The content of this material specification page was compiled from available public sources and authorities on material properties. Although we believe the information to be corrrect, Metal Stock, Inc. is not responsible for the accuracy of any of the material specifications and only presents this data as general information for our customers.

C1144 Stressproof® is a carbon-manganese grade, which is severely cold worked to produce high tensile properties. The bars are specially treated to relieve the stresses set up by the cold drawing, thus minimizing the tendency towards warpage after machining, which is common in ordinary cold drawn bars. Stressproof ® cold roll bars have a built-in high strength hardness without the need of heat treatment. Stressproof® has the combination of free machinability, minimum warpage, high strength, and wearability not found in ordinary metals.

 

General Information about C1144 Stressproof®:


APPLICATIONS:

C1144 Stressproof® applications include; cold punched nuts, split rivets, machine and wood screws, arbors, keyed shafts, motor shafts, splined shafts, drive-shafts, armature shafts, rotary pump shafts, gusher pump shafts, oil and water pump shafts, wrist pins, pinions, piston rods, arbors, spindles, gears, sleeves, lead screws, racks, link pins, mandrels, boring bars, collets, bushings, etc.

MACHINING AND WELDING:

C1144 Stressproof® machinability is rated at 83% of B1112. Average cutting speed is 140 ft/min. Because of a very high sulphur content, weldability is considered poor and not recommended.
