Passivation Type Call-Out





What different types of passivation are there?. The print call-out says per QQ-P-35 type optional. The material is 304L

QQP35 has four types, two of which are recommended for 304.

You can read it at http://assist.daps.dla.mil/quicksearch/

Also note that QQ-P-35C [affil link or DLA] has been replaced by ASTM A967 [affil link] and SAE/AMS2700 [affil link] for aerospace, both of which allow citric type passivation as well as the nitric. Let us know if we can help.
