heat treatment

Disassociated Ammonia Atmospheres

are used in the following heat treating applications where protective atmospheres are required:

  • ​Bright annealing and brazing of high alloy steels, magnetic steels and rare metal
  • ​Bright tempering of castings​
  • Sintering of powders
  • ​Nitriding of steels​​
  • Carbonitriding
  • ​Furnace brazing
  • ​As a substitute for pure hydrogen in annealing processes
  • ​Sodium Hydride descaling
  • Atomic Hydrogen welding
  • Any application where it is absolutely necessary to avoid surface oxidation
  • As a substitute for exothermic and endothermic-base atmospheres when a smaller output is acceptable

Advantages of Disassociated Ammonia Atmospheres

  • High quality
  • High purity
  • Nitrogen and Hydrogen can be used for any purpose without further treatment
  • Transportation and handling of ammonia cylinders is not difficult
  • Ammonia contains no oxygen
  • Ammonia liquid and vapor is lighter than water and air
  • The Hydrogen and Nitrogen produced by decomposition is cheaper than other methods
