Inconel 693 P number

Inconel 693 P number

Inconel 693 P number

(OP)
I am trying to locate the P-Number for Inconel 693 (UNS N06693). The material is not listed in ASME Section II-D, however the UNS number falls under SA-166. If anyone have any experience in determining P numbers for unlisted material, your help would be greatly appreciated.

RE: Inconel 693 P number

If the P-No is not listed in ASME Section IX, QW-422 which it is not, the material should be listed by the UNS number for WPS qualification and welder performance qualification.

RE: Inconel 693 P number

(OP)
We have a WPS for P43 to P43 material which list typical materials as SB-166, SB-167 and SB-168. Since I found that Inconel 693 falls under SB-166, can I conclude that the weld procedure is good for this material eventhough ASME does not identify the material as P43?

RE: Inconel 693 P number

No. Just identify the material on the WPS/PQR by the UNS number.
