Nitriding is a heat treating process that diffuses nitrogen into the surface of a metal to create a case-hardened surface. These processes are most commonly used on low-carbon, low-alloy steels.However, they are also used on medium and high-carbon steels, titanium, aluminum and molybdenum.n the plasma nitriding processes, nitrogen gas (N 2) is usually the nitrogen carrying gas. Other gasses like hydrogen or Argon are also used. Indeed, Argon and H 2 can be used before the nitriding process during the heating of the parts to clean the surfaces to be nitrided.
