Dear Sujith kumar, 

please refer API RP 582 for consuables selection

and below consubales are refered by API  

1.  ERNiCrFe-2 or -3. &   ENiCrFe-2 or -3.

2.  ERNi-1 & ENi-1.

check with consumable manufacturer they may suggest some other newly developed consumables based on this application  

However, it is highly recommended to use Nickle base consumable (Ni-1) as it is suitable consumable for NI200 alloy welding and better to avoid SS consumable for this joint as it may create crack on Ni alloy side due to dilution in the weld.

Regards,
