Comparison between symmetric and asymmetric hot rolling techniques performed on Duplex Stainless Steel 2205

For these reasons, the asymmetric rolling, for many years have been considered as unsuitable. Nonetheless, asymmetric rolling can provide also some advantages: decrease the average rolling pressure, decrease the rolling force and the related torque, improved surface properties of products.
Beside, asymmetric rolling involves interesting and favourable consequences on the microstructural features associated to the increase of shear stress strain penetration at the core layers of the machined strip. Several authors have investigated the asymmetric rolling for aluminium alloys, but not information are present about applications of this technique for the rolling of duplex stainless steel grades.
