Hot Tip
MIL QQP35C has been replaced by ASTM A 967.  This means that citric acid passivations of stainless steel are approved for what were formerly MIL spec. nitric acid passivations only.

Passivation
If you deal with the passivation of stainless steel on a regular basis ASTM A 967 and ASTM A 380 are two of the most important documents you will ever own on the subject.  These documents can be ordered from www.astm.org/
