What is MIL-STD-171 184.108.40.206 or 220.127.116.11
Q. I do the purchasing and quoting for a small job shop and am trying to find out what 18.104.22.168. or 22.214.171.124 of Mil-STD-171 [link is to free spec at Defense Logistics Agency, dla.mil] is. I would greatly appreciate any help.Greg T [last name deleted for privacy by Editor]

A. Greg, you can find Military Specifications on the web pretty easily- currently
http://assist.daps.dla.mil/quicksearch/ works, but if the DoD changes it just type in "Military Specification" in Google, and you'll get there. Anyway, in Revision E, paragraph 126.96.36.199 deals with Chemical Agent Resistant Coatings (CARC), and there is no 188.8.131.52. Perhaps your request refers to an earlier revision of Mil-Std-171.
Ed. note: The Assist site has moved many times over the years, so we are now using active macros to link directly to the specs in question, as below ...
A. Mil-STD-171 [link is to free spec at Defense Logistics Agency, dla.mil] E concerns Phosphate finishes for iron & low alloy steels.
184.108.40.206. is Phosphate Type M per DOD-P-16232 [ed. note: replaced by MIL-DTL-16232 [link is to free spec at Defense Logistics Agency, dla.mil]].
Class 2, is with a supplementary treatment with lubricating oil conforming to MIL-L-3150 [ed. note: superceded by Mil-PRF-3150 [link is to free spec at Defense Logistics Agency, dla.mil]], and 220.127.116.11. is Phosphate Type Z per DOD-P-16232 Class 2 with preservative conforming to MIL-PRF-16173 [link is to free spec at Defense Logistics Agency / dla.mil] , grade 3 or MIL-L-3150 (as alternate for very small parts) Hope this helps.Marie M [last name deleted for privacy by Editor]

A. Marie M's answer is the correct one! Mil STD 171 is the standard for industry to coat bare metals to a certain specification for the Department of Defense. MIL-STD-193 is the standard for CARC.

A. Sorry, I was lost as Lee was, because this spec has a section 188.8.131.52, but that's not not what you are talking about . . . you are talking about finish number 184.108.40.206 and 220.127.116.11, from Table V
Although phosphated parts that are not oiled usually get painted, I don't see this specification demanding that they be painted.
