Tufftriding QPQ

Tufftriding QPQ (Quench Polish Quench) is a heat treatment process that enhances wear, fatigue and corrosion properties of any ferrous material, but with minimal distortion owing to the low process temperature of 580°C. These benefits result from the formation of an intermetallic compound (epsilom iron nitride) on the surface of the treated component, strengthened and supported by the diffusion of nitrogen.


Benefits of low temperature nitro-carburising:

  • High Corrosion Resistance
  • Increased fatigue strength
  • Low co-efficient of friction
  • High wear resistance

Quench

When quenched to develop the full properties, treated parts have a characteristic matt black finish and for many applications no further treatment is necessary.

Polish

When operating against plastic or rubber seals, soft bearing metals or simply because a superior cosmetic appearance is required, the components are polished.

Quench

Optimum colour and corrosion properties are restored by a short passivation treatment in the quench bath.
