The heat rolling the billet of the production methodological null ferritic stainless steel of the ferrite

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a ferritic stainless steel sheet excellent in ductility and ridging resistance with which the ferritic stainless steel sheet excellent in ridging resistance and the ductility can be produced without the need of the additional process.;SOLUTION: In the method for producing the ferritic stainless steel sheet, having a process in which a steel slab of the ferritic stainless steel is hot-rolled and thereafter, the hot-rolled plate is annealed, pickled and cold-rolled, and the cold-rolled sheet is annealed, the above annealing to the hot-rolled plate is performed under condition of the soaking heat-treatment at ≥950°C for 6-12 hr.;COPYRIGHT: (C)2006,JPO&NCIPI
