There are yield strength values reported for UNS No32750 under SA-790 (Specification for seamless and welded pipe intended for general corrosion service). The SA-240 Specification is for plate, sheet or strip for pressure vessels and general applications.
Per ASME Section II, Part D, Table Y-1;

150 deg F 74 Ksi
200 deg F 70.5 Ksi
250 deg F 67.4 Ksi
300 64.7
400 60.7
500 58.3
600 57.2
650 57
to 750 57

Sorry, but you need to perform the conversions and interpolate accordingly.
