Re: [MW:7079] F-No&A-No of ERNiCrMo-3

For ERNiCrMo-3 Fnumber is 43, please recheck WPS if they have specified some other filler such as NiFeCr-1, NiCrMo-9 falls under F45.
A Numbers are not applicable for non ferrous welds

No such condition as for P number/F Number should be same in Sec IX.

Construction Code - ASME B31.3
Welding Code - ASME BPV SEC IX
 
What is the F - No. of ERNiCrMo-3?  43 or 45?One of the  WPS in my hand says 45 !!!
I have reviewed ASME BPV SEC IX QW 432,F-No. section and found that 43.Now I need clarification from experts,which one is correct 43 or 45?
 
What is the A - No. of ERNiCrMo-3? I have reviewed QW 422 A-Numbers section,but couldn't find.
 
Is there any condition that P- no. and F- no. shall be same?
