General Metal Heat Treat

Information may not be reliable

As part of our high-quality heat treating processes, General Metal offers annealing heat treatment services. Think of annealing as the opposite of hardening. We anneal metals to soft them, refine grain structure, and make them more pliable. Annealing is a heat treatment process where a metal is heated to a specified temperature–sometimes slightly above the metal’s critical temperature–then we hold the temperature for a set period of time, then cooling the metal to room temperature. The method of cooling will largely depend on the properties desired. In order for the annealing process to be successful the cooling period has to happen slowly, and with great care.
