Electropolishing Stainless Steel Specification

ELECTROPOLISHING APPLICATIONS AND TECHNIQUES
Electropolishing is known to improve the passivity or corrosion resis-tance of stainless steel. As evidence of this, the latest version of ASTM A 967 recognizes electropolishing as an accepted method of pas-sivation. While the phenomenon of passivity may not be fully under-stood, there is evidence that free iron is removed from the outer few ... Access This Document

Electroplating

Control Electropolishing Corporation
Control Electropolishing Corporation has been providing exceptional electropolishing service since 1959. Unlike electroplating, which adds a layer of material to the surface, electropolishing is the controlled removal of inconsistent surface material. Passivation, which is a natural by-product of electropolishing, makes surfaces corrosion-resitant. ... Retrieve Content

Electropolishing | Industrial Metal Finishing| Anoplate, Inc.
Electropolishing is the process of smoothing and/or brightening a metal surface anodically in a concentrated acid or alkaline solution. Anoplate is set up to perform it on either Stainless Steel or other Nickel rich alloys. While it can be done on many base metals as a preplate operation, it is commonly done on Stainless Steel as a final finish. ... Fetch Document

What Is Electropolishing? | New England Electropolishing
Passivation is often misunderstood as it’s a benefit of electropolishing but can also be accomplished without electropolishing through chemical means. At NEE, we use the traditional Nitric Acid passivation process. Chemical passivation doesn’t alter the visual appearance or surface finish (Ra, RMS) of stainless steel. ... Read Full Source

Is Electropolishing Better Than A 2B Surface Finish?
Many of Marlin’s clients ask if finish or coating “X” is better than finish or coating “Y.” In most cases, the answer will depend on the client’s precise application for the coating or finish. Recently, one client asked whether a 2B stainless steel surface finish, as specified in ASTM A480, is better than or equal to an electropolished or passivated finish. ... Doc Viewer

Black Oxide - Wikipedia
Black oxide or blackening is a conversion coating for ferrous materials, stainless steel, copper and copper based alloys, zinc, powdered metals, and silver solder. It is used to add mild corrosion resistance, for appearance and to minimize light reflection. To achieve maximal corrosion resistance the black oxide must be impregnated with oil or wax. ...
