摘要

Disclosed is a method for manufacturing a steel sheet for making a JCO steel pipe and a JCO steel pipe. An aspect of the present invention provides a method for manufacturing a steel sheet for making a JCO steel pipe by cooling a heated steel sheet, wherein cooling is conducted so that rapid cooling regions and slow cooling regions can be formed alternately in the widthwise direction of the steel sheet during the cooling, and the rapid cooling regions and the slow cooling regions are parallel to one another in the lengthwise direction of the steel sheet.
