Heat Treating Definitions:
Annealing - A generic term used to describe the heating, holding and cooling of metallic materials. It is used to softern, improve machinability, and increase dimensional stability.	Stress Relieving - Uniformily heating steel or iron, to a suitable temperature where the residual stress is reduced. Then cooling slow enough to minimize the development of new stress.
Flame Hardening - A heat treating method in which pre-selected areas of the part being treated are heated by direct flame impingement prior to quenching.	Normalizing- The process of heating steel or iron to a temperature above its transformation range, followed by cooling in still air.
Carbonitriding - A heat treatment for steel which adds carbon and nitrogen to the surface from a gaseous atmosphere rich in these elements.	Hardening - A heat treating process designed to increase the hardness of a material. It involves heating to an austenitizing temperature, holding for uniformity, and cooling at a rate fast enough to develop high hardness.
Induction Hardening - A form of hardening in which the heating is done by induced electrical current.	Carburizing - Adding carbon to the surface of steel by heating it in contact with carbon-rich gases.
