Ammonia Systems for Heat Treatment

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
