It is recognized for offering high quality and environment friendly salt bath nitriding process services, which are preferred by a large number of clients throughout the country. All the services are available at market leading prices and within the expected time frame by customers. Salt bath nitriding is a thermo chemical process in which nitrogen and carbon are diffused simultaneously into the surface of the material.

The high concentration of nitrogen chemically combines with iron and other nitride forming elements to produce an outer layer of epsilon iron nitride, which is thin, hard and ductile. This layer is also known as the compound zone, which has increased surface hardness to enhance anti-galling characteristics, and lowers the coefficient of friction. This compound zone also functions as a solid film lubricant by providing a non-metallic interface between mating surfaces. Nitrogen of lower concentration continues to diffuse below the compound zone and forms a solid solution with the base metal iron. This zone is referred to as the diffusion zone and is noted for its improvement in fatigue strength.
