Abstract：The composition characteristics and process requirements and application of a cold rolled sheet for chain are briefed，the microstructures of hot rolled and cold rolled sheet are analyzed，and the comparison test with import steel from Japan is studied.The result of the actual mass production and application indicates that based on C-Mn,the technology route with increasing Mn content and reducing C content is applied,and with suitable Si content,the cold rolled steel sheet chain possesses high tension and good wear-resisting property and high precision through suitable technological processes，appropriate for shift bicycle and motorcycle. The microstructure, properties and thickness precision of the steel have reaceed the user’s requirements .
