Abstract: The influence of high/low finish-rolling temperature on the formability and ridging of Nb micro-alloyed 17%Cr ferritic stainless steel sheet was investigated by using metalloscope, XRD and EBSD (electron back-scattered diffraction). Based on finish-rolling temperature of 930°C and 810°C comparison, the results showed that, for the cold-rolled and annealed sheets, the low finish-rolling temperature is beneficial to the alleviation of the deviation from exact <111> fiber axis, strengthening γ-fiber texture at different layers along sheet thickness, with textural homogeneity improved and a less frequent formation of orientation colonies in the finished sheets. Therefore, the finished sheets which were hot rolled at low finish-rolling temperature may enhance their formability with ridges reduced.
