That would be my guess. Now Titanium would be really cool to use but talk about cost! We also used Hastalloy in the AF on the F16 after burner het shields and that metal was a bear to weld and to grind but I am sure that would hold up amazing as a glue not to mention a great conversation starter haha.
I'm sure you can weld it, it's the question of what happens at the weld. One major problem, is where do you get 316Ti welding rod? You'd probably have to use a 316L rod so what happens where the two materials meet in that weld? I don't know, but I'd sure research it before doing it...
Hastalloy is good stuff... Make a chimney out of that, it would outlast your building! LOL

It would be cool to report to this site my findings every year. It is so hard to find accurate information on products these days as many people have different experiences and some companies will obviously stretch the truth to sell a product, especially for more money. But in the case of the company I am dealing with they are putting their money where their mouth is. Chimney people are wierd in VA I had one qoute that wanted 5000$ to reline my chimney and use Portland mortar and Portland based filler and they totally didn't know what they were talking about regarding the use of Portland in a lime mortar chimney... If I didn't know better they would have destroyed my chimney! It's scary how some companies are allowed to practice!
The 316Ti should work just fine. It's a good alloy. I'm sure the way they are putting it together will work out well for you. If I were building chimneys as a contractor, I wouldn't put in steel without lots of not just fine print but bold print!
