        Grain-size numbers of 5 and lower can create a visual surface problem called orange peel. Remember that the grain boundaries are stronger than the grain interior. When the steel is stretched to large strain levels, the grain boundaries resist deformation and allow the core of the grain to deform (Fig. 1). This obviously is not acceptable for a Class A surface, so some companies will specify a grain-size number of 6 or finer on their purchase orders.
