17-7 ss wire heat threating options
(OP)
Hello to all Engineers!
We have two spring makers proposal using 17-7 ss wire, condition C to be meet blue print load requirement: Option 1: heat threat to 900F for 30 minutes and Option 2: Heat threat to 750F for 1 hour. Which one is right? Your comments Please, if any one had similar project.
Thanks.

the standard ultra-high strength aging heat treat of 17-7ph is H900 (1hr@900F)
I have the feeling that 750 is below the activation energy for the preciptation to occur. While 900F for 1/2 hr might get what you want, it may not develop the proper distribution and size of the preciptates.
