Roll systems integrated in industrial temper rolling lines introduce bending deformation that can lead to plastic deformation on the strip. When setting the optimum temper rolling degree, bending deformation is usually not taken into account. In this project, the effect of plastic bending deformations on the mechanical strip properties was investigated at laboratory scale. For low carbon steel, bending deformation influences the mechanical strip properties in a similar way as skin pass (SKP) rolling itself. However, the minimum in yield strength is obtained for higher degrees of plastic deformation by bending compared to what is obtained after pure temper rolling. Concerning the suppression of the yield point elongation (YPEL), the same effects are achieved for bending and rolling deformation modes. It can be concluded that it is necessary to take into account plastic deformation induced by bending through the skin pass rolling line.
