Do we have to expect degradation of the mechanical properties or something similar? If your vendors must comply with AMS Method 1, Type 2, one suggestion is that the parts be cleaned better before passivation because some people claim that even minuscule traces of oils can cause this etchingperhaps by generating some sort of organic acid which etches the parts. 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.

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

During forming, machining, tumbling, lapping and other operations performed in the manufacture of stainless steel products, microscopic particles of iron passivatikn be embedded in or deposited on the surfaces of these products. Can you please tell me the differences between the passivation processes AMS [link by ed.

As far as the stainless steel passivation process itself, you’re pretty much always going to work your way back to A Precision Machining Technology Show. In the ASTM A and the nitric acid concentrations mentioned must be percentage by volume of a reagent of 67 wt. This auditor you are a,s with, what organization is he with? This is actually an oversight of A that will be corrected in the next revision.

ASTM A967 vs. AMS 2700? Which is the right passivation spec?

Thank you for your hard work which the finishing world continues to benefit from. But I have a Problem with the steel 1.

This is important because you can probably solve the problem by changing the spec to citric acid passivation, electropolishing, or ajs else if you are the author of the requirements and you are not in aerospace.

The 3 consensus specifications used at this time, and that should be used for all specifications of passivation are:. This has been a hit and miss for us with the different companies.

We design our own parts, and do our own passivation in house, and hence prefer the testing requirements of ASTM A All The specifications are the same, then why are the Names different? A discussion started in but continuing through Q. From beautiful Pine Beach New Jersey: Determining the suitability of A for your specific parts is up to you, or requirements set by your customer.

But if it’s a medical instrument or implant, then you’re also going to have to show the appropriate tribute to an F standard.

To me this means volume percent of pure nitric acid, resulting in significantly stronger passivation solutions than AMS Is one better than another for medical devices?

My customer wants to put A on his print for standard passivation, but my plater tells me that he passivates to A Santa Clara Plating Co. Experts affiliated with SAE International include those in industries like commercial vehicles, automotive and aerospace—all industries for which Passivaton Electropolishing provides stainless steel passivation.

AMS 2700 Passivation Standard

Based on the previous information, the concern is regarding the minimum requirements in A Especially in the fastener industry I have seen it is difficult to source a specific product according to a specific type within these standards. November 27, — this entry appended to this thread by editor in lieu of spawning a duplicative thread A.

AMS Passivation Standard As a global paasivation of engineers and other technical experts, SAE International provides consensus-formed standards that help define the best practices for processing aerospace, automotive and commercial vehicle components—including metal am services.

Electropolishing and Passivation Standards. Passivation restores the corrosion resistance of stainless steel parts. ASTM A renumbered those to nitric 1 through 4, while AMS brought back the ones that had been removed and has types 1 through passivafion.

Created with Webvanta CMS. Which is the right passivation spec? QQ-PB contained six nitric acid bath Types. Is your business surgical implants, or are you with a passivation shop, or what?

One of the differences is in the definition of ‘a lot’ for testing purposes. If you are interested, click the link next to my name and you can get my contact information, then I can direct you to my distributor in Germany. FebAnaheim, CA. Lee Kremer has pointed out that A is not a Specification, only a Practice. Method 1 is subdivided into 8 Types corresponding to the types in old QQ-P while Method 2 is not subdivided.

Ray, Thank you for answering. Rest psasivation peace, Ken.
