David339933 you have a good point.

I found this article regarding Nitrogen anneling. Could be the desired treatment of the forgings.
Baseicly you stait that we have to follow ASTM A182 for heat treatment.
As far as my technical knowlages are Stabilization is similar to Normalization.
As A182 point 10.1 is writen that Stabilization for F347 must be prerformed:
- Subsequent to the solution anneal for Grades F 321, F
321H, F...
We have to proqure ( WN flanges 16"600LBS XS in A182 F347 + N ).
The producer in China proposed this Solution Annealed at 1080℃ firstly , then carried out Stabilization at 880℃.
But in A182 is not the same and also there is noting writen for Normalization in the standard for this grade F347...
