Resistant to Stress at High Temperatures

Ni-Resist piston rings are ideal where effective operation at high temperatures and corrosion resistance are critical. Ni rings are especially resistant to stress relieving at high temperatures.


  • Thermal expansion coefficients are very similar to stainless steels, which makes Ni-resist piston rings especially ideal in exhaust applications.
  • The corrosion resistance in Ni rings is far superior when compared to normal and low alloy cast irons, gray iron, ductile iron and steel.
  • Outstanding ability to resist the combined effects of corrosion and erosion in high velocity applications.

  • Corrosion Resistant
  • Wear resistant
