PURPOSE:To obtain the stainless steel strip having low surface roughness with good productivity by rolling by carrying out the final annealing of the stainless steel strip plate in a nonoxidizing atmosphere to limit the grain size, and then cold-rolling. CONSTITUTION:At least the final annealing of stainless steel is carried out in a nonoxidizing atmosphere to dispense with the pickling under conditions where the grain size is regulated to <=20mu, and the stainless steel is subsequently cold- rolled. High-strength stainless steel strip plate with improved surface roughness can be obtained in this way. Meanwhile, if the stainless steel wherein working-caused martensite is not generated is not used, excellent surface roughness equal to that of the rolled stainless steel can be obtained. The stainless steel plate obtained by this method has excellent surface gloss, and is smoothly plated with less detects when the surface is treated by plating, etc. Accordingly, the stainless steel is also suitably used as the substrate for a solar cell. |
