The process of Nitriding plays a crucial part in various industrial components and directly affects the performance of their final products or services

What Is Gas Nitriding and Nitrocarburizing

Nitriding (N) and nitrocarburizing (NC) are thermochemical treatments that diffuse nitrogen and carbon into the surface of metals. Nitriding is used on ferrous, titanium, aluminum, and molybdenum alloys, and most commonly on low-carbon, low-alloy steels. Nitrocarburizing is only used on ferrous alloys.

Nitriding is typically carried out at 450 to 520°C and nitrocarburizing at 540 to 580°C. These treatments are below the tempering or stress-relieving temperatures of steel, which are over 600°C. Therefore, the processes cause little or no distortion.

What You Get

They improve surface properties of metal components and tools such as scuff and corrosion resistance, and increase the fatigue strength.

Nitrided layer will wear with time depending on
the contact stress. It withstands temperatures up to 400ºC but this depends on the type of steel. Steels with higher content of chromium-molybdenum and vanadium have the highest resistance to temperature. Nitrided parts do have much higher resistance to temperature than carburized steels. Low temperatures do not affect nitrided layers if the steel itself does not become brittle.
