Parts in the Pumping Industry:
- Plungers
- Pistons
- Valves
- Gears
- Screws
- Impellers
- Rotors
- Shafts
- Bushings and Sleeves
- Case Rings
Requirements for the parts:
- For high Hardness
- For high Wear resistance
- For high Fatigue strength
- For Plastic deformation resistance
- For Lower friction
Ion Nitriding Solutions:
Significantly increasing the surface hardness, wear resistance and fatigue life of the parts, improving their lifespan and performance.
- Reducing the friction coefficient.
- Increasing the corrosion resistance.
- Post-Oxidation can be done after nitriding in the same process for further increase in corrosion resistance.
Improving these parameters will save from downtime and maintenance costs.
Steel Grades Used:

Hardness and depth values are recommended for the industry and exact values will depend on the nitriding process parameters.
