PROBLEM TO BE SOLVED: To provide a manufacturing method which can stably suppress the occurrence of edge cracks of a Cr-Ni-based stainless steel strip caused during hot rolling.;SOLUTION: After grinding a continuously cast slab into a shape in which the thicknesses in width end parts are thickened as compared with that in the middle part of the width, when making the ground slab into a hot-rolled steel strip by performing hot rolling in a process of (heating-rough rolling-finish rolling), the rolling in the width direction is definitely performed by odd numbered pass in the rough rolling and is performed at the edging quantity in rolling of the width direction, which is defined by the next formula (1), of ≥7 mm in any pass.;COPYRIGHT: (C)2010,JPO&INPIT
