摘要： Hot rolling is performed on a steel with a predetermined composition containing Ti: 0.0020 mass % to 0.010 mass % and/or Cu: 0.010 mass % to 0.50 mass % to obtain a hot-rolled steel sheet. Annealing is performed on the hot-rolled steel sheet to obtain an annealed steel sheet. Cold rolling is performed on the annealed steel sheet to obtain a cold-rolled steel sheet. Decarburization annealing and nitridation annealing are performed on the cold-rolled steel sheet to obtain a decarburized nitrided steel sheet. Then, finish annealing is performed on the decarburized nitrided steel sheet. When obtaining the decarburized nitrided steel sheet, heating on the cold-rolled steel sheet is started in a decarburizing and nitriding atmosphere, then first annealing is performed at a first temperature within a predetermined range, and then second annealing is performed at a second temperature within a predetermined range.

摘要： A slab with a predetermined composition is heated at 1280° C. to 1390° C. to make a substance functioning as an inhibitor to be solid-solved (step S1). Next, the slab is hot-rolled to obtain a steel strip (step S2). The steel strip is annealed to form a primary inhibitor in the steel strip (step S3). Next, the steel strip is cold-rolled once or more (step S4). Next, the steel strip is annealed to perform decarburization and to cause primary recrystallization (step S5). Next, nitriding treatment is performed on the steel strip in a mixed gas of hydrogen, nitrogen and ammonia under a state where the steel strip runs, to form a secondary inhibitor in the steel strip (step S6). Next, the steel strip is annealed to induce secondary recrystallization (step S7).
