Passivation Standards




1999

I'm trying to understand the development of standards in the area of passivating stainless steel.

I'm been told that QQ-P-35C [link is to free spec at Defense Logistics Agency, dla.mil] has been cancelled and is being replaced by ASTM A967 [affil link] -96. Also, MIL-DTL-14072 [affil link or DLA], E300 directly calls up ASTM A380 [affil link] . I have then been told that A 380 and A 967-96 might merge, so perhaps another standard will be created?

Can anyone kindly verify / counterclaim my understandings?

Thanks alot,

Bob

Bob, We have doing a lot of Passivating, Over the last couple of years, Some of the changes that have happen is that

1. QQ-P-35 was cancelled then for some reason ( probably confusion) AMS picked up the same spec Lists it as AMSQQP35 [canceled, affil. link]

2. ASTM A967 [affil link] spec is still in effect as been in the last couple of years and it is soon to be revised just to confuse things even more -- chris

Bob, be careful with the type of work you're doing for QQ-P-35 The spec has been superceded by ASTM A967 [affil link] or AMSQQP35 [canceled, affil. link]. If you are performing military and aerospace work you have to use the AMS specification which is identical to the original QQ-P-35. Only the controlling publisher has changed to SAE. The ASTM 967 was written to take the place of QQ-P-35, but has lost some of its power with the release of the SAE AMS spec. I haven't heard any gossip on the formation of a new spec (ASTM)

Bob ASTM A967 [affil link] Is the replacement for QQ-P-35C if your process conforms to QQ-P-35C it might be that your process is conforms to the new standard .The new ASTM A967 [affil link] Is not focused in the process solution but in the process results and requirements which are similar to the previous standards.

Where can I get QQ-P-35 (Type 11.) and MIL-A-8625 / MIL-PRF-8625 [affil link or DLA] (Type I, Class II )? I want to know the meaning/content of these two spec.

I'm located in China, but I need to make some components with this U.S. Spec.

Appreciate your response.

Does the new ASTM A967 [affil link] spec use the same "types" and "classes" as the QQ-P-35?

I'm confused with this thread, for to do a passivation treatment a stainless steel, should you use specification # MIL-F-14072-E300 or use AMSQQP35 [canceled, affil. link].
