Identification of surface features on cold-rolled

Introduction Control of surface finish is a major concern in the man- ufacture of stainless steel strip. Prior to the cold-rolling operation, the hot band is annealed, shot-blast and pickled, leaving a comparatively rough and broken surface, as illus- trated in the scanning electron micrograph of Fig. 1a.
