Nitriding

When nitriding, workpieces are exposed to a nitrogen discharging environment with a temperature of 480° to 520° C. Nitrogen coming from the split ammonia diffuses into the surface of the workpieces.
With this treatment you will – depending on the material – reach a surface hardness of up to 1,200 hv1.
Wear, corrosion and hardness can be directly optimised, and there will be no changes in the core material. Only the surface layer is modified, leading to a very good measurement and form stability. Typical nitriding steels are 1.8519; 1.8550; 1.6580.
