Heat treating is a thermal process used to alter mechanical and chemical properties of metal objects. Most magnetic shielding components require heat treating to restore and/or enhance magnetic shielding performance, so it only makes sense that MuShield operates a heat treating facility on-site. MuShield utilizes hydrogen heat treating furnaces, which yield superior shielding quality in the heat treated piece parts. Magnetic shielding components are heated to 2100°F in a dry hydrogen atmosphere and eventually cooled back down to room temperature. Hydrogen is a reducing gas and removes surface impurities such as carbon and oxygen. The resulting metallurgical structure produces maximum permeability and shielding effectiveness.
