Abstract: Provided are a chain component that has a simple surface treatment structure and can maintain good wear resistance over a long time, and a chain that includes the chain component and maintains good wear elongation resistance. The chain component of a power transmission chain for industrial use includes a chromium nitride layer formed on an outer side of a steel base material and containing more than 0 mass % but not more than 55 mass % iron. At least a surface of the chromium nitride layer that slides against other components is a rough surface with peaks and valleys.

Abstract: To provide a versatile and easy-to-produce link plate that can mitigate the rise in surface pressure on guide members even when the link plate is slightly tilted, to minimize adverse effects of wear marks and wear particles, and a chain. The link plate has a sliding end face, with end face rounded portions at both ends in a direction of plate thickness, formed to be continuous with both side faces of the link plate. The link plate is shaped to satisfy 16.8≥((r*2/t2)+(t−r*2))/r≥11.5, where r represents a minimum radius of curvature of the end face rounded portions and “t” represents the plate thickness of the link plate.
