Heat & surface treatment

Heat treatment

Gas nitriding

The process of adding nitrogen to the surface of a steel usually from dissociated ammonia as the source. Nitriding develops a very hard case after a long time at comparatively low temperature, i.e. 480°C to 530°C without quenching. No further heat treatment is necessary.

  • High wear resistance against abrasion and adhesion
  • Little distortion
  • Creation of corrosion resistant layers
  • Reduction of coefficients of friction
  • High temperature strength and tempering resistance of the surface layers to about 500° C
