What is Annealing?

Annealing requires heating to and holding at a suitable temperature and then cooling at a suitable rate for such purposes as reducing hardness, improving machinability, facilitating cold working, producing a desired microstructure (for subsequent operations) or obtaining desired mechanical, physical, or other properties.* 

Gasbarre specializes in the design and manufacture of custom-engineered annealing furnaces specific to the thermal processing industry.
