Influence mechanism of annealing after hot rolling on surface ridging in ultra-purified ferritic stainless steel

The hot rolled sheets and the hot rolledannealed sheets of an ultra-purified Cr17 ferritic stainless steel stabilized with Nb and Ti were cold rolled and annealed in the same way,and the influence mechanism of annealing after hot rolling on surface ridging of the finished sheet was studied in terms of microstructure and micro-texture evolution.It was shown that the hot rolling deformation texture and the texture gradient along transverse...
