This article deals with the relationship between the mechanical properties of the products andthe proportion of velocity and the rolling pressure as well during the S asynchronous rolling ofconstant elongation. The authors have analysed the affect of shear strain on the mechanical pro-perties of products of the asynchronous rolling on the basis of the kinematic and mechanical con-ditions and microstructures. In conclusion, the authors have given a basic method controlling themechanical properties of the products by means of controlling the proportion of velocity and therolling pressure under the conditions of the S asynchronous rolling.
