ASTM A967 General industries use this standard to describe and control the passivation of stainless steel. Passivation is a process of making stainless steel more stainless than it would be if left alone.
A. ASTM A967 [affil link] is often specified for passivation of titanium, although it is a misnomer for sure. What you are removing by "passivation" of titanium is any iron or iron oxide that may have been put on the surface in the fabrication process of the parts. Even though you do not truly passivate the titanium metal itself, you need to
