What is AMS Passivation?


In reading through the specification I believe the drawing is incorrect. Do the parameters in A cover any worst case scenario? Electropolishing and Passivation Standards.

Both contain a carryover of QQ-PC with the addition of the more recently developed citric acid based process. Is this a correct assessment? October 23, A.

Ken Vlach – Goleta, California. AMS exempts C from testing. To me this means volume percent of pure nitric acid, resulting in significantly stronger passivation solutions than AMS There are other in-house specifications for some companies.

All information presented is for general reference and does not wms a professional opinion nor the policy of an author’s employer. I replied that the parameters are in compliance with standard A but he’s telling that we don’t have objective evidence to support the validation since A defines minimum requirements that could be insufficient to my process.


AMS Method 1 Type II Passivation for Medical Device

If you’re having it done for you, the testing is someone else’s problem, so you might consider AMS But our favorite choice would be Type 8. As far as the additives, they aren’t absolutely necessary, but I like to think they do help quite a bit, since that’s essentially what my product is.

A has a lot of excellent recommendations on general cleaning etc. We appended your question to a thread passivvation should clearly answer it for you: The two standards are essentially equivalent. You’ll probably see for yourself why it’s not a good idea.

From beautiful Pine Beach New Jersey: Jan, Both standards are based heavily on the old QQ-P There are other differences- ASTM A allows the use of any mix of nitric and water, so long as you show it works Nitric 5 solution.

We will check for issues with solution entrapment and other design concerns.

ASTM A vs. AMS vs. ASTM F86? Which is the right passivation spec?

December 19, A. June 11—13, Chicago, IL. In the ASTM A and passivaion nitric acid concentrations mentioned must be percentage by volume of a reagent of 67 wt.


Especially in the fastener industry I have seen it is difficult to source a specific product according to a specific type within these standards.

AMS 2700 Passivation Standard

Indeed also my conclusion is that it is an omission. Citric passivation does have the advantage that if you set it up properly, you can use one bath to handle all your different grades.

This is actually an oversight of A that will be corrected in the pzssivation revision. 200 simple terms, he’s saying that given 2 SS surfaces which have different concentrations of free iron, the chemical reaction will take longer in the surface with more free iron. He passed away May 14, It appears that the types are associated with method 1, not method 2.

As you see, we added your question to a thread which already answers it. Many OEM passivation specifications are derived from these guiding documents.
