Gas Nitriding/Gas Nitrocarburizing

Gas Nitriding or Gas Nitrocarburizing is a case-hardening process whereby nitrogen is introduced into the surface of a solid ferrous alloy by holding the metal at a suitable temperature in contact with a nitrogenous gas, usually ammonia.

Benefits include:

  • Extends part/tool life
  • Adds performance, fatigue strength and endurance
  • Enhances surface lubricity
  • Reduces erosion
  • Increases material flow in molds and dies
  • Improves corrosion resistance
  • No post-process machining
  • Improves wear resistance
  • Zero to minimal growth/distortion
  • Precise and versatile
  • Phase controllable compound zone

Recommended for:

  • Stainless steels
  • Tool steels
  • Powdered metals
  • Medium carbon steels

Nitriding and Nitrocarburizing

Nitriding and Nitrocarburizing are performed at lower temperatures than conventional heat treatments, which minimizes distortion.
These heat treatments improve wear resistance, fatigue strength, and corrosion resistance.

Nitriding/Nitrocarburizing Types:

  • Ion Nitriding (Plasma Nitriding / Nitrocarburizing)
  • Gas Nitriding (Gaseous Nitrocarburizing)
  • Salt-Bath Nitriding (Liquid)
