ASME B31.3 CHPT IX ASTM A694 F65 at design temp. 65¦C

[17092003]

Hi all,

Can someone provide guidance to determine the value of Syt (yield strength at temperature) in accodance with ASME B31.3 CHPT IX K302.3.2 (c) (1). In other words Ry needs to be found.

Due to the application forging ASTM A694 F65 is being considered. This material is an unlisted material in ASME B31.3 CHPT IX and ASME II part D.

The thread330-257765 covers part of the above.

Thanks.
