Based on AISI 304H chemical composition and it's position on Schaeffler diagram, using ENiCr-3 is best choice instead of ER309 bare wire.

Dear All
Regards
Kindly clarify the doubts:
Sir in Ethylene Cracker Furnace at one of the Petrochemical Plant, we have a hook-up between P-91 and SS304H. Here we are using ER309 as the filler.
Is it acceptable, if not what can be the probable problems associated with the filler selection and what are the solutions
