A similar mechanism can occur in stainless steel rolling, where the shot-blast finish on the hot band prior to rolling tends to generate pits on the surface during subsequent deformation. Oil trapped in the pits can be drawn out due to the sliding between the roll and strip, as illustrated in Figure 4.1.
