  • What surface finishes are available on stainless steels?

    The importance of surface finish in determining the corrosion resistance of the stainless steel surface cannot be overemphasised. A rough surface finish can effectively lower the corrosion resistance to that of a lower grade of stainless steel. Cold rolled, heat treated, pickled, pinch passed. Cold rolled and bright annealed, still
