Re: [MW:32616] Re: Which Filler wire to be used in between P43 (Inconel 625) to P8 (A240 310S) by GTAW)

For the first point the filler you can used ER Ni cr Mo-3

For dish head after cold forming it depends  on fiber elongation of material usually 5 to 10 fiber elongation PWHT is required and above 10 Normalizing and tempering is required.

As per my understanding For P43 Filler wire ER NiCrMo-3 is suitable as per chemical and mechanical properties.
