Abstract: A chain component which has a simple surface treatment structure and in which satisfactory wear resistance is maintained for a long term; and a chain which employs this chain component so that a satisfactory wear elongation resistance is maintained are provided. A roller chain serving as an industrial chain for power transmission is constructed such that a pair of outer plates linked by two pins and a pair of inner plates linked together by two bushes onto each of which a roller is fit are alternately linked together in a plurality in a state that each pin is loosely fit in each bush. A chromium nitride layer is formed on the outer side of the steel-based substrate of the pin. The chromium nitride layer contains iron at a content higher than 0 mass % and lower than or equal to 55 mass %.
Abstract translation: 具有简单的表面处理结构并且长期保持令人满意的耐磨性的链组件; 并且提供了使用该链组分从而保持令人满意的耐磨延伸性的链。 作为用于动力传递的工业链的滚子链被构造成使得通过两个销连接的一对外板和通过两个衬套连接在一起的每对内衬板彼此交替地连接在一起 在每个插针松动地配合的状态下。 在针的钢基底板的外侧形成氮化铬层。 氮化铬层含有含量高于0质量％且低于或等于55质量％的铁。

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.
