PROBLEM TO BE SOLVED: To provide a corrosion-resistant chain capable of demonstrating excellent chain strength and wear resistance without losing the strength of components of the chain, suppressing white rust on chain components in the corrosive atmosphere, eliminating chain's bending failures apt to occur between link pins an bushings and bad appearance of chain components, and consequently demonstarating corrosion-resistance for a long time. SOLUTION: A corrosion-resistant chain 110 comprises bushings 12 respectively press-fitted to bushing-press-in holes 11a of a pair of left and right separated bushing link plates 11 and chain pins 14 respectively inserted loosely into the bushings 12 and press-fitted to pin-press-in holes 13a of pin link plates 13. The bushings 12 and chain pins 14 are respectively coated with an Sn-Zn alloy by a hot-dip Sn-Zn plating. COPYRIGHT: (C)2008,JPO&INPIT
