1144 Stress Proof Steel Bar

1144 stressproof steel, a carbon-manganese grade with highly developed tensile properties, is available in our product inventory to be used for a wide range of applications.

Stainless Steel Bar

1144 stressproof is a product out of the proprietary process in which bars are drawn through a special die under a heavy draft. The process relieves stress in a precisely controlled furnace. 1144 is a carbon-manganese grade severely cold-worked to develop high tensile properties.

Stressproof is electromagnetically tested with the use of eddy currents. Stresses are relieved when bars are treated through cold drawing. This set up minimizes the tendency of warping after machining. In addition, this process also develops the bar’s high strength hardness without implementing heat treatment.

1144 stressproof exhibits good mechanical properties coupled with an excellent combination of free machinability, high strength, minimum warp, and good wear resistance which ordinary metals don’t have. The effective setups done to produce stressproof cold rolled bars to make them meet super stringent standards invariant applications.

1144 has this variety of advantages upon use:

  • High strength without heat treatment
  • Extended tool life
  • Balanced working
  • Controlled low stresses
  • Enhanced wearability without case hardening
  • Excellent surface quality
  • Fatigue and stress resistance
  • Exceptional machinability
  • Minimized distortion and warpage

1144 stressproof round bars can be turned, ground, and polished for each of their designated applications and depending on requirements of each use.

1144 bars are often used in manufacturing the following components and parts:

  • Motor shafts and keyed shafts
  • Drive-shafts
  • Machine and wood screws
  • Cold punched nuts
  • Rotary pump shafts
  • Oil and water pump shafts
  • Gusher pump shafts
  • Splined shafts
  • Split rivets
  • Arbors
  • Pinions and piston rods
  • Wrist pins
  • Gears and sleeves
  • Racks and link pins
  • Lead screws and spindles
  • Collets and bushings
  • Mandrels and boring bars
