Electropolishing 416 Stainless Steel




I am currently trying to electropolish 416 Stainless Steel in order to remove any burs and/or machining marks. The parts are flat surfaces with multiple small holes (250 microns in diameter and deep) in the face. What would be the best process/bath chemistry to achieve a polished surface without significant damage to the holes? Any information or guidance would be greatly appreciated.

400-series stainless steel is well polished by our ACIDFREE electropolishing technology. Electrolyte is based on saline solution, safe for the environment, easy to regenerate and to recycle. Sharp blades are not damaged during polishing. Passivation is not required after polishing.
