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.

Why choose MuShield for your hydrogen heat treating needs?

  • Having in house heat treating capabilities improves lead time and quality
  • Already have a finished good that needs to be heat treated? MuShield does not only heat treat our own parts, but also offers hydrogen heat treating service on outside parts on a contract basis.
  • We can hold up to 200 pounds of material and have retort sizes measuring 20″ x 20″ x 40″
  • MuShield is an approved heat treating vendor for many companies in the military, medical and aerospace industries including BAE, NASA, Johnson and Johnson, Raytheon, JPL to name a few.
