MIL-F-14072

A. Bruce, from looking at MIL-F-14072, page 39, it sure looks like "E300" is passivation per ASTM A380 (and then I'd try to weaselword some way of using ASTM A967 instead, as it is the newer specification for passivation).

You can download military and federal specs from http://assist.daps.dla.mil/quicksearch/ ^ ^{https://quicksearch.dla.mil/}

Hope this helps...

A. Hi, James. I tried as well and was also unable to find that particular spec on the assist site for unknown reason. But it is available from a commercial site and we've now included the link. Good luck.

Regards,

 I did find that M217 is for Hot Tin Dip. I got that from an ex-NASA employee and a shop in California.
Thanks for trying...

A. Hi Michael; more words please :-)

You want to obtain the spec (it's not a spec, it's just a code within spec MIL-14072), or you want someone to process parts for you to that spec, or you want to buy the paints & processes?

... or you want guidance on what "P510.2N" is supposed to mean?
Table I of MIL-DTL-14072 says that "P510.2" means MIL-DTL-5541 chromate conversion coating of aluminum, followed by MIL-PRF-23377 [on DLA] primer. The "N" might mean color black semi-gloss MIL-PRF-22750 topcoat per the list of abbreviations in Table II, but I don't know whether the convention is to just append an "N" to the code that way or not.

Luck & Regards,
