The experiments of cold rolling were made using stainless steel (SUS430) sheets and three kinds of lubricants in viscosity with rolls polished by #800 polishing paper in the axial direction in the 1st pass, and with rolls polished by #800 one in the axial direction and by #2000 one in the random direction in the 2nd pass. Then, the surface features of sheets rolled in the 1st and the 2nd passes were investigated to discuss the improvement of the surface characteristics of sheets rolled in the 2nd pass. As a result, it has been shown that the 2nd pass rolling with rolls polished by #2000 polishing paper in the random direction after the 1st pass rolling with rolls polished by #800 one in the axial direction gives the disappearance of the nearly linear defects in the normal direction to the rolling one, which occurred in the 1st pass rolling, and gives the increase of surface gloss by using the lubricants of lower viscosity.
