What titanium alloy grade that have the highest ultimate tensile strength and corrosion resistant to
inorganic acids like hydrochloric,hydroiodic,hydrobromic,nitric,sulfuric phosphoric and pure elemental halogen like bromine chlorine,iodine.
Also Hydroflouric acid if is resistant

Grade T82, ....it is highly resistant to everything ..... You can trust me ...!!!

Understand, Sergei,... you must never, ever use a "please or thank you", ... It takes up far too much of your precious time to use these simple words, Serg !!

I suggest that you just rudely demand complex and specific information from others .... Use all CAPS on occasion !!

Have a nice day, buddy !!!

I want to know what is the standard ASTM name of the titanium alloy?
 
Ur...

Typically Highest UTS and highest corrosion/chemical resistance cannot coexist... these are tradeoffs: Highest UTS = lowest corrosion resistance... and Vice-versa... especially in the chemicals you listed.

All those acids? mixed or pure? in what concentration? at what temperature? etc etc...
 
A lot more details needed.
The issue is usually that high strength alloys rely on aging for strength and the precipitates that form in aging are often much less corrosion resistant than the bulk alloy.
This leaves highly corrosion resistant alloys being single phase and lower strength.

Grade T82, Buddy .... You are welcome !!

MJ... OK, You repeatedly stated 'Grade T82'.

HOWEVER... I am left scratching my little-old-aerospace brain. I thought I knew most titanium alloys and related specs... but 'Grade T82' simply does NOT compute.

Soooo, please advise... Grade T82 titanium >>>>>> is in WHAT specifications????

As a place to start look at Gr 28, 29, and 20.
These are versions of age hardenable alloys that contain Ru or Pd to enhance corrosion resistance.
Be warned, the corrosion resistance is highly environmentally specific.
And the trace additions (0.1% or 0.05%) of these metals more than doubles the raw alloy costs.
