Atmosphere Heat Treat

• Perfectly suited for smaller production volumes or unusual designs
• Atmospheres include Nitrogen, Hydrogen, and Argon
• Employs a torch to heat the joint and melt the filler material
• The joint is protected from oxidation by using filler materials that melt well below the oxidizing temperatures of the parent materials
• Versatile technique which produce consistently high-quality connections
• With the exception of a few metals such as titanium, zirconium and certain stainless steels, most can be torch brazed

Annealing

Annealing is a process involving heating and cooling, usually applied to produce softening of the metal to facilitate machining or forming operations. The term also refers to treatments intended to alter mechanical or physical properties, produce a definite microstructure, or remove gases. The temperature of the operation and the rate of cooling depend upon the material being annealed and the purpose of the treatment.

Tempering

Tempering, sometimes called Drawing, is the process of re-heating hardened steels to reduce hardness and increase toughness. The tempering temperature depends upon the desired properties and the purpose for which the steel is to be used. Increasing the tempering temperature will reduce the hardness of the steel while increasing the toughness.
