Springs

Compression Spring

Open-wound helical compression springs precision coiled from SS316 or Inconel wire.

Precision open-wound helical springs engineered to resist compressive forces applied axially. Coiled on high-speed CNC spring formers using premium spring-temper alloy wire, with squared and ground ends for uniform load transfer.

Key benefits

Why this product

  • Inconel 718 and Hastelloy-C grades maintain spring rate and resist relaxation in boiling acids
  • Precision ground flat ends ensure perpendicularity and prevent side-buckling in mechanical seal pusher assemblies
  • Shot-peening treatment induces compressive surface stress, increasing cyclic fatigue life by 300%
  • Custom spring rate (N/mm) matching available for valve relief and pressure regulator calibration
