I received a Luxfer tank from a friend that is hydroed for another year or so. What's strange is that the tank is made with the 6351 alloy. I thought that these tanks could no longer be used because it was susceptible to sustained load cracking. She said though that it was "eddy" tested and that it was okay to be used. I just want to be sure that this thing that is completely safe (and legal) to use for diving.

Really depends on who you talk to. If you do a search for 6351 you will see a lot of threads on it. Our shop won't fill them, and a lot of shops won't, but some due - so read a bunch, and then it's up to you and the local shops if they will fill it.

The long and the short isn't whether or not it's still good, the issue is whether you cna get a fill. More and more shops won't fill them - As Larry said. I can't blame them.

I agree with the others that I would personally stay away from it just because of how much hassle they can be. It is just not worth it for the cost of a new one.

Is it safe??? Probably, with the proper inspections. Worth the hassle??? Not to me

Thanks everyone. After reading some of the posts in those links you posted, navyhmc, I've decided that I'm just going to return the tank to her. Like you guys have said, even with a current hydro it's not worth the hassle to try and find a shop that will fill it.

And not only that - it's not worth the risk either.
