Electropolishing

Electropolishing Stainless Steel Electropolishing is the ultimate process in the surface finishing of stainless steel and produces a superior finish with unique properties. The process is carried out by immersion in a tank with an electrolyte and a rectifier. Having the opposite effect of electroplating the process removes a layer of material between 5 to 40 um (microns). As the process has no impact to the surface the process solution temperature is far below and the critical structure formation zone. This renders the surface pure, chemically clean and thus, undisturbed crystalline structures are exposed. These surfaces have several features and characteristics unmatched by any other finishing process.

Micro Finishing

The flow of the current and the natural action is to remove the peaks at a faster rate than in the troughs on the surface topography, leading to the elimination of micro roughness and has a further feature of deburring. Additionally, the surface is super smooth, making it hard for deposits and residues to attach themselves, which makes the surface exceptionally easy to clean.

Increased Corrosion Resistance

Selective removal of iron enriches the surface with Chromium and Nickel. Oxygen is liberated at the anode (positive) side of the electrolytic process and theses gases flow upwards reacting and oxidising recently expose layers thus further improving the corrosion resistance.

Ultra Clean

Electropolishing Steel Process By removing the damaged and contaminated surface layers the process exposes pure crystalline, ultra clean base material. This restores the original properties of the material and makes the surface suitable for ultra-clean applications. Further more, external surface stresses in the upper layers are relieved. Component sizing may also be undertaken by employing tightly controlled parameters.
