This specification covers the requirements for an epsilon-iron nitride case on ferrous parts produced by immersion in a low-temperature, agitated, fused salt bath.

Nitrocarburized surfaces have been used typically for increasing the resistance to wear and fatigue on ferrous alloys including carbon steels, low-alloy steels, tool steels, and corrosion-resistant steels, cast irons, and ferrous powder metal products, but usage is not limited to such applications.

This process is not recommended for use on parts that have been plated with silver, copper, zinc, or cadmium or on parts having copper alloy inserts.

While the materials, methods, applications, and processes described or referenced in this specification may involve the use of hazardous materials, this specification does not address the hazards which may be involved in such use. It is the sole responsibility of the user to ensure familiarity with the safe and proper use of any hazardous materials and to take necessary precautionary measures to ensure the health and safety of all personnel involved.
