Nitriding steel

Livallco offers many types of nitrous steel for hardening the surface layer of the steel component.

Nitriding steel is a specific material used to nitrate and harden the steel surface. Common use for nitriding is for treatment of small gears, crankshafts and wear parts. We can supply all types of nitrous steel – even specially adapted products – with short lead times.

How does nitriding work?

Nitriding is a heat treatment process that increases the nitrogen content in the surface of the steel and creates a hardened surface layer. The process is reminiscent of case hardening, but is carried out at lower temperatures.

There are many benefits to nitriding:

  • The steel that is nitrided has reduced dimensional changes compared with traditional carbonization
  • Nitration does not give an equally thick curing depth compared to case hardening
  • Nitration can also increase the corrosion resistance of a component
