RE: Nimonic 75
What heat treatment was it given?
What final HT condition do you need it in?
The HT of these alloys is complex, you need to be careful.

air cooling. This material is basically unaffected by heat treatment.
RE: Nimonic 75
Any suggestions,are welcome.Thank you!
RE: Nimonic 75
I would try the stress relief I mentioned above between 440 deg C to 475 deg C (840 to 890 deg F) for between 1/2 to 1 hour after rough machining versus 1976 deg F (1080 deg C).
