Gerald,
Thanks. The nickel. And quite frankly I'm surprised the nickel steel BM, even as Q & T is better than the 625 filler. Though I've never done cryo impacts on 625. I can see the lateral expansion of the weld being better than the HAZ with a Q & T though, if that is what you intended. If not, it doesn't make any sense to me. Your water Q and then T is essentially gone in the HAZ, essentially turning the Q & T into a normalize. Which might enhance the impact s'trength' over the nickel base filler, as your post indicates. Its all a bit confusing, but the numbers are certainly good enough in any case. Thats the bottom line.
But then, thats why you do the tests.
Very interseting. This one is going in my file. Thanks
