PURPOSE: Ferritic stainless steel and a manufacturing method thereof are provided to obtain superior quality in the shape of ferritic stainless steel through multi-stage correcting processes. CONSTITUTION: A manufacturing method of ferritic stainless steel includes subjecting ferritic stainless steel, passing through an annealing process(S2), to the following temper mill process(S3), surface finishing process(S4), and shape correcting process(S5). When the ferritic stainless steel is parallel to the direction of a rolling roll used for a rough rolling process, the glossiness of the ferritic stainless steel at the light reflection angle of 60°is controlled to the range of 150-420. The shape correcting process is repeated two to five times. |
