Welding Chrome-molley valves to 304 SS Pipe
(OP)
I'm looking for some guidlines to help me select filler metals for welding dissimilar metals. Specifically SA-182 F22 (P-5A) to SA-312 TP 304 Seamless Pipe (P-8). I would like the resource so I have a way to look this up in the future and would welcome any input on my delima at hand. Thanks!!

Use ER/E309 for welds not requiring PWHT or operating below 500 F to 600 F.
When PWHT is required or the operating temp is greater than 500 F to 600 F, use a nickel base alloy filler metal; eg., ENiCrFe-3 or ERNiCr-3 or similar.

Stanweld has given the right answer. If your service permits, I will add use TP 304 flanged valves and use F22 flanges on your P22 pipe to make the connection between your valve and your pipe.
