[MW:533] Filler metal for P 11 (O/L SS 347) to P8

Dear Member,

 

Can some body give his/her opinion for filler metal of following condition?

 

Branch connection (Tube Side) between LWN flange (Material SA 182 F321) to SR Nozzle (SA 182 F11 CL 2 + Weld Deposit 347 SS).

 

Service is Hydrogen.

 

Operating Wall Temperature - Tube Side is IN 372° C & Out 225° C.

 

Also recommend the filler metal for the first layer of weld deposite.

 

Thanks in advance
