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
