Question abour heat treatment of PH stainless steels
(OP)
Does anyone know why section 3.4.3.1 of AMS 2759/3 explicitly states that for PH stainless steels, only one resolution heat treatment is permitted? I don't recall any other specifications mentioning that, and from a metallurgical/microstructural standpoint, I can't think of any detrimental effects of resolutioning more than one time.

Since none of the anneals are above 1900F the risk of grain growth is limited.

The exact thermomechanical path is different for various alloys, but many times we reanneal and even age between forming or drawing operations.
When we get to the end we anneal and age, if we don't hit properties then we one more chance.
That is how I read it.
