Vacuum Anneal For Machining

is a general term which refers to a variety of processes which produce a softer metal. It is a heat treatment wherein a material is altered, causing changes in its properties such as strength and hardness. It is a process that produces conditions by heating to above the re-crystallization temperature and maintaining a suitable temperature prior to cooling. Annealing is used to induce ductility, soften material, relieve internal stresses, refine the structure by making it homogeneous, and improving cold working properties. NATIONAL HEAT TREAT has 2 furnaces for this process.
