DEFINITION

Classification: 164/57.1

Adding metal-containing material:

420, Alloys or Metallic Compositions, appropriate subclasses for alloying processes. In Class 420, an alloying processes is classified with the composition of the specific alloy made. Subclasses drawn to processes of making alloys are: 18+, processes of adding magnesium to cast iron; 29+, processes of making cast iron; 71, processes of making over 9 percent chromium steel, e.g., stainless steel; 84+, processes of adding lead, bismuth, selenium, tellurium or calcium to ferrous alloys, usually to improve machineability; 115+, processes of making low chromium steel; 129, general processes of making ferrous alloys; 590, general processes of making alloys.
