Nitriding Fluid : Meproche 5151

Nitriding basically is employed to avoid distortion during heat treatment and also provide a wear resistance surface.

Carburizing can achieve good case depth and high hardness, but it involves distortion.

Nitriding on steels can achieve good wear resistance and practically no distortion, but it gives very low case depth and comparatively low hardness.

There are administrative problems in storage and purchase of Ammonia to create atmosphere of nitrogen, hence Meproche 5151 can be used. This is easy to store and can be drip fed.
