I was wondering who was currently doing any Grade 91 and what they were seeing pertaining to casting spec requirments on NDE and repairs as well as how the vendors are responding to these requirements.

I have a few customers that do a bit of 91, but i don't think i have ever seen a casting in their shops, forged flanges and O-lets mostly

They are starting to get stringent on forgings and castings due to flaws, and doubts about microstructure, and viability. Historically the required testing has been less than it should be.
