SCC in Condition C
SCC in Condition C
(OP)
Anybody ever hear of a formed 17-7 part cracking due to SCC while in Condition C, prior to the CH-900 heat treatment?

Maybe there is some similarity.

Is there a chance for chloride contamination during the process?

I recall that 17/7 was one of the alloys that failed very quickly. The problem is I can't recall the heat treated condition of the 17/7 part tested.
We found quite a few of the PH alloys susceptible to SCC in molten salt baths of the type we used for cleaning. We took this as warning to be very careful of the enviroment that any of the PH alloys was exposed to.
The slight rusting of your spring is unusual for a 17/7 part.

When do you peen the parts?
Is there a reason that you can't form and then age right away?
Even aged you are going to need to protect the parts somewhat. The CH900 condition isn't known for corrosion/cracking resistance.
