Mechanical Polishing - using various forms of abrasives and grinding and polishing tools (including unique adaptations) mechanical polishing is the primary method for meeting a required surface roughness (Ra) on a metallic surface.

Passivation - per ASTM A-380 includes a pre-cleaning part to remove residue from manufacturing followed by a nitric acid or citric acid exposure for the purpose of removing any free iron from the surface and allowing a chromium enriched oxide surface to form which provides optimum corrosion resistance for the surface finish.

Pickling - using concentrated acid pickling removes heat scale, weld scale, heat discoloration from stainless steel alloys

Electropolishing - an electrochemical process that smooths and levels metallic surfaces to a degree only comparable to a "lapped" finish which is provided using extremely fine "diamond" particles in a slurry form such as is used in preparation of laboratory metallurgical samples and on precision "gage blocks".

Electrochemical Cleaning (ECC)SM - the use of electropolishing techniques to remove "rouge", stains, product residue, grey residue common on mechanically polished stainless steel surfaces.

Electrochemical Passivation - per ASTM B-912 uses electropolishing techniques to simultaneously remove surface contamination from manufacturing and forming a chromium rich oxide surface that when properly rinsed and allowed to dry provides a passivated state equal to or in some cases superior to conventional passivation methods.
