If allowed to remain, the iron particles provide corrosion sites that will ultimately result in accelerated corrosion of the product. You can guess the increase in the amount of testing involved.

One of the differences is in the definition of ‘a lot’ for testing purposes. Thanks for your time.

ASTM A – Passivate – Passivation – AMS – QQ-PC – ASTM A | Santa Clara Plating

This has been a hit and miss for us with the different companies. Is there any clear direction or is it optional? It was cancelled in early in favor of AMS Of course testing with your parts against desired performance levels is recommended as well.

If the part passes the verification test, what differences in function can occur in the part’s use if differing acid baths are used? What should I tell my customer?

But our favorite choice would be Type 8. From beautiful Pine Beach New Jersey: Is your business surgical implants, or are you with a passivation shop, or what? If you do not specify, they can use whatever they want, even ways that are not in any of the specifications!

Santa Clara Plating Co. We are set up for this process but not the high concentration-high temp nitric process. Electropolishing and Passivation Standards. Regards, Ted Mooney, P. We appended your question to a thread which should clearly answer it for you: 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.

Since you’re considering an AMS spec, I assume you have aerospace customers.

If you’re having it done for you, the testing is someone else’s problem, so you might consider AMS Always specify exactly what you want– e. It’s not possible to diagnose a finishing problem or the hazards of an operation via these pages. Experts affiliated with SAE International include those in industries like commercial vehicles, automotive and aerospace—all industries for which Able Electropolishing provides stainless steel passivation.

ASTM A renumbered those to nitric 1 through 4, while AMS brought back the ones that had been removed and has types 1 through 8. In reading ASTM A and AMS it seems that there is quite a bit of overlap but with differences in the bath variables or verification requirements. Lee Kremer has pointed out that A is not a Specification, only a Practice.

FebAnaheim, CA. Our services remove free iron and other contaminants on the surface of stainless steel parts, creating a passive surface with increased corrosion resistance. November 7, A. AMS considers different parts, or the same part made at different times, to be different lots with the exception for parts with the legacy QQ-P called out, when you can use the older definition.

To me this means volume percent of pure nitric acid, resulting in significantly stronger passivation solutions than AMS Do you have any experience in passivating parts unlike in the AMS suggestions? Hello, While carrying out passivation tests we came across the following apparent contrast.

Specifically, this standard refers to the requirements for removing surface contaminants like free iron from the surface of corrosion-resistant steel parts. A renumbers those to 1 through 4 there is no such thing as A Type 6 or 7 while restores the missing four for a total of eight Types.

David, Go ahead and try a small piece of in the Type 8 bath. Passivation restores the corrosion resistance of stainless steel parts. April 12, A.

We design our own parts, and do our own passivation in house, and hence prefer the testing requirements of ASTM A He passed away May 14,
