In regards to post-forming heat treatment of SA-179 U-bends for a thickness of <= 0.134" via
Soak time (15min) at temperature (1150°F)(ASME Section VIII, Division 1 UCS-56)
vs
Brought to temperature via electric resistance (no soak time) to temperature (1150°F)
1. Has anyone studied the effects of hardness and grain structure analyzing the differences between the two?
2. Can anyone point me to an article describing the differences?
Thank-you.
