Vacuum Gas Nitriding Furnace by Therelek

Therelek’s gas nitriding furnaces produce the most appropriate condition for all applications. The furnaces are specially designed for gas nitriding of tool steels which happen to be limited to applications like the hot work tool steels, and also tooling for the aluminium extrusion dies.

The gas, during gas nitriding, is disposed of to a metal via heat in the furnace or sealed atmosphere and has easier disposal methods of the nitriding agent. Some of the key advantages that the vacuum gas nitriding furnaces by Therelek provide are as follows:

#Precise temperature control 

#Control over depth, hardness and dimensions

#Total coverage of nitriding including holes and bores

#Apt for the handling of large quantities of small pieces

#Works apt for alloy steels and low carbon steels

Features

  • Fast gas cooling arrangements.
  • Exhaust gas neutralizers.
  • HMI with touchscreen operation.
  • Excellent process repeatability.
  • Very dense bulk load.
  • Low maintenance costs.
  • Gas exhaust cracking (optional Analyser NH3)
  • Excellent process repeatability.
