ABSTRACT:
A hinge conveyor chain includes at least two links, each of the links include a pin engaging surface for engaging a pin hingedly coupling the at least two links together. A pin hingedly coupling the at least two links includes an outwardly facing surface slidably engaging at least one of the pin engaging surfaces of the at least two links. One of the outwardly facing surface and the at least one pin engaging surfaces of the at least two links is formed from a steel alloy with at least about 2.5 wt. % Cu and the other of the outwardly facing surface and the at least one of the pin engaging surfaces of the at least one of the at least two links is formed from a stainless steel.
