This specification covers the passivation by electropolishing of stainless steel alloys in the, and series, as well as precipitation-hardened alloys.

By maintaining tight control of our processing parameters, we are able to continue to meet the rigid guidelines of the ASTM, providing our clients not only with superior results in a timely fashion, but also peace of mind that their work is in good hands. Customer Quotes “We asm never had an issue with Classic Electropolishing.

For a metal finisher to meet these standards for stainless steel passivation, they must adhere to specific protocols and ensure a particular quality of work. Electropolishing and Passivation Standards. Quote Your Next Project. AeroDef April 30 adtm May 1 Gain access to the technologies and people in aerospace and defense manufacturing.

Electropolishing standards are used by a wide variety of industries. Precision Machining Technology Show. Historical Version s – view previous versions of standard. No other units of measurement are included in this standard.

Free iron on the surface of the stainless steel is removed resulting in improved corrosion resistance. At Classic Electropolishing quality finishing and polishing is paramount, both to us and to our customers. We do not have any trade shows on our calendar presently, we will update our calendar soon. Because Able Electropolishing adheres to the ASTM B electropolishing guidelines for stainless steel passivation, our clients know what quality of work to expect when we process various types of stainless steels.


May 15 — 16, B921, MA. It covers both the passivation of stainless steel and the precipitation via electropolishing. These factors and others determine eligibility for meeting this specification.

Some industries classify the process using standards outside of ASTM.

Website by Dan Voell. Gain access to the technologies and people in aerospace and defense manufacturing. Standard ASTM B applies to pre-electropolishing cleaning and post-electropolishing coating such as a dip and rinse process. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Post-coating g912 such as post dip and final rinsing shall be performed as well.

If you are an engineer working on a drawing just add the astmm note to your product “passivation per ASTM B” and we will know what to do. Reach out to us electropolished on Twitter. This abstract is a brief summary of the referenced standard.

ASTM B912 Electropolishing Standard

Electropolishing will also remove heat tint and oxide scale. Basis materials shall be free of clearly visible defects, and if necessary, shall undergo preparatory cleaning procedures prior to electropolishing.

Classic Electropolishing adheres to the following additional standards: Classic Electropolishing provides passivation services adhering to ASTM B, passivation using electropolishing for stainless steel series, stainless steel V, stainless steel and stainless steel series.


Surface smoothing obtained by electropolishing will also improve corrosion resistance. It is informational only and not an official h912 of the standard; the full text of the standard itself must be referred to for its use and application.

ASTM B Passivation Using Electropolishing

The ASTM B electropolishing specification outlines the electropolishing process for stainless steel alloys. What Does This Mean? Able Electropolishing meets the high standards of the American Society for Testing and Materials ASTMincluding those for stainless steel passivation using electropolishing. According to the ASTM, the electropolisher must include post-coating procedures as part of the process, as well as performance testing by means such as a salt spray test, a humidity test or a copper sulfate test.

It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. The performance of the specimens during passivation shall be evaluated by one or more of the following procedures: ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

The quality of passivation will depend on the type of stainless steel, the formulation of the electropolishing solution, and the conditions of operation.
