Liquid Nitriding

Liquid Nitriding

In Liquid Nitriding/salt bath nitriding the nitrogen donating medium is a nitrogen-containing salt. The salts used also donate carbon to the workpiece surface making the salt bath a nitrocarburizing process. The temperature used typically for all Liquid Nitriding processes is 550 to 570°C. Its field of application includes gears & pinion shafts, plastic injection molding screws and barrels, piston rings, aluminum extrusion dies, forging and forming dies, spindles for grinding machines, gun barrels, springs, crankshafts and camshafts, plastic mould and other wear components.

Why Liquid Nitriding?

The main advantage over other means of surface hardening is the low process temperature. Parts can be machined to final dimensions and do not need costly finishing work after this treatment.

Other advantages are:

  • Quick processing time
  • Simple operation
  • low risk of distortion

Almost all material can be treated.

The hardness varies as per the type of material.

In Liquid Nitriding, treatment time is generally within a day. Final timing depends on the desired case depth & size of the steel parts.

We charge based on the weight (kg) of material, however, pricing depends on the maximum number of pieces that can be treated at once. For details, please contact us.
