We have experienced an increase in hardness and a loss of ductility on some of the oldest components. These can be restored to the proper hardness range by an over-aging treatment.
We have other 17/4 components that are used in weak nitric service where we use Gr8 class 2 fasteners. We have no appreciable problem with corrosion or galling.

The alloy does require very careful control over heat treatment so make sure that your sources have good track record.
