Re: [MW:24275] Alloy Material P22, A335 (Cr2.25 and Mo 1)

you could use a "B2" filler metal. The next issue in filler metal selection is the use of post weld stress 

relief which is not mentioned. If the weld is going to be subjected to a post weld stress relief then use 

an ER80S-B2 and if there will be no post weld stress relief you should consider ER70S-B2L.
