Titanium itself cannot be damaged by solvents or ammonia. The coating the factory puts on it might be damaged but the titanium won't be. It's not possible. There are of course different grades of titanium. But titanium is used for metal implants put in the mouth and for prosthetic implants used in hips, knees and shoulders. Body fluids including blood are highly caustic and very corrosive and don't effect the implants at all. The only fault titanium does have is that it work hardens and becomes brittle and then will crack or shatter. That's why titanium hammers that used to be installed in 1911 competition guns were such a failure. They would work harden and break off after 1000 or so rounds. But struts, firing pins and mainspring caps continue to this day and work very well.
