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
