DEFINITION

Classification: 428/659

(under subclass 658) Subject matter in which the zinc-base component is adjacent to a component having 40 percent or more of iron.

(1) Note. The mere designation of a composite as "galvanized" is sufficient for placement in this subclass.

(2) Note. Patents classified herein are not cross-referenced to subclasses 681 or 933 on the basis of the Zn/Fe interface.
