The present invention provides a ferritic stainless steel rolled steel material excellent in corrosion resistance and toughness, particularly suitable as a material for a flange, a method of manufacturing the same, and a flange part. The ferritic stainless steel rolled steel according to the present invention is characterized in that it contains 0.001 to 0.08% of C, 0.01 to 1.0% of Si, 0.01 to 1.0% of Mn, 0.01 to 0.05% of P, 0.0002 to 0.01% of S, To 25.0%, N: 0.001 to 0.05%, the balance being Fe and inevitable impurities, and having a plate thickness of 5 mm or more and having a cross section parallel to the rolling direction at an arbitrary point between the left and right ends of the steel sheet Is in the range of 15% or less from the rolling direction is 20% or more. |
