148, Metal Treatment, appropriate subclasses for processes of treating solid or semi-solid metal to modify or maintain the internal physical structure (i.e., microstructure) or chemical properties of metal. If metal casting, fusion bonding, machining, or working is involved, there is a requirement of significant heat treatment as described in section III, A, of the Class 148 definition.
219, Electric Heating,
600+, for inductive heating, subclasses 678+ for microwave heating, subclasses 764+ for capacitive dielectric heating, and subclass 162 for methods of electrically heating metal.
264, Plastic and Nonmetallic Article Shaping or Treating: Processes, 345+, for methods of treating a shaped or solid nonmetallic article by means of a temperature change.
432, Heating,
9+, for processes of heating to treat an article, container, or body as an unit.
