Bluewater’s Ferritic nitrocarburizing (FNC) has a high resistance to wear, excellent scuffing and seizure resistance as well as improved corrosion resistance. While Ferritic Nitrocarburizing is the more generally specified process, the greater load bearing capability of the Austenitic treatment has resulted in its adoption as an attractive alternative to the high temperature surface hardening techniques.
Ferritic Nitrocarburizing is often selected to replace chrome plating or shallow case carbonitriding. FNC is a low temperature process that can be performed without distortion or loss of precise dimensional requirements. Ferritic nitrocarburizing creates a shallow surface layer of epsilon iron nitride compond that typically has a hardness ranging between 58-65 HRC. This compound layer also increases the base materials resistance to corrosion.
