Marty,
Excellent, thank you. Agreed that the drop in FN after solution anneal is not detrimental, but expected. As you pointed out, I also believe that heavy walled pipe, as the thicknesses you demonstrated, will tend to experience IGSCC at a more frequent rate given a "higher" heat input. Thankfully, technology has changed somewhat since the '70's. Avesta's stand on heat input is recommended at 38,000 J/in, but like you, I normally tell folks 35,000 J/in so as not to push the limits. I will check out the web site you shared. Thanks for sharing. This has been a very informative and interesting thread. Good info, Marty, thanks..
Chuck
