Gas Nitriding or Hard Nitriding or Classical Nitriding


Gas Nitriding is a process of case hardening in which steel is being heated in an atmosphere of ammonia gas at a temperature of 490 degree celsius to 550 degree celsius generally (500-520) for a prolonged period, at this temperature ammonia gas dissociates to produce atomic nitrogen. The atomic nitrogen diffuses into the steel forming nitrides, produce a hard wear resistant surace free from scale containing the minimum distortion. Karbotherm is the first company in Ghaziabad offers Gas Nitriding Services, this process in nature is very lengthy compared to other process and hence costly.


Benefits that can be realized through Gas Nitriding Treatments:-

  1. High Surface Hardness up to 68 HRC can be achieved.
  2. Favoured for components that are subjected to heavy loading.
  3. Liquid Nitriding imparts a high surface hardness which promotes high resistance to wear, scuffing, galling and seizure.
  4. Fatigue strength is increased mainly by the development of surface compressive stresses.
  5. Hot hardness and resistance to heat.
  6. Adhesive Resistance for extrusion dies, moulding dies and hot work steels.
  7. Improved Superior wear resistance, excellent friction properties and excellent corrosion protection and Good surface fatigue resistance.
  8. Very Low or none distortion.
