DEFINITION

Classification: 148/505

Utilizing therein factors or percentages related to metal or

metal alloy composition (i.e., including carbon content):

(under subclass 500) Process wherein a mathematical formula or relationship utilizes factors or percentages related to a metal or alloy composition including all materials whether metal or not (e.g., carbon content).

(1) Note. For this subclass, the mere use of percentages or moles utilized to define a metal or metal alloy composition is not sufficient by itself for placement herein. An actual mathematical formula or relationship must be present which includes as a part thereof factors or percentages related to the composition.
