The present invention provides a manufacturing method of a mixed stainless steel sheet including a first and a second grade stainless steel sheets. Stainless steel sheets are sorted into a first grade and a second grade according to the existence of defects. The manufacturing method of a mixed stainless steel sheet reduces the number of the second grade stainless steel sheets, which cause lack of weight of a coil. According to the manufacturing method of a mixed stainless steel sheet, a marking line (100) for distinguishing the first grade sheets form the second grade sheets is formed on the surface of the stainless steel sheet in the widthwise direction of the stainless steel sheet before the stainless steel sheet on which the first grade sheets and the second grade sheets are mixed is wound to be the coil. |
