HEAT TREATING

Dissociated 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 metals
	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 Dissociated 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

Our equipment dlist includes the cylinder manifold, ammonia storage and delivery system, vaporizers, skid packages, controls, and monitoring equipment. All of our equipment is ANSI/ASME approved for use in ammonia heat treatment applications.
