Haynes 214 is one of the new generation of "superalloys" (as some people like to call them). Inconel 625 has been around for a long time and is probably one of the first to carry that label. Both have similar characteristics so I'm guessing that Haynes 214 is an enhanced derivative. Looking at the spec sheets the biggest difference I see between the two is the much higher aluminum content in H 214 (4.5% vs. .4%)--chromium is 16% and 20% respectively.

We did a couple Inconel jobs many years ago and as far as I can remember it welded pretty much like SS--just had to have the right filler rod and maintain the correct temperatures. I imagine that the high aluminum content of the H 214 is what will make it tricky.

Usually when there are materials like this involved there are also hovering engineers; have they not specified a welding process? Also, Haynes has quite a bit of information on their website; I assume you've already contacted them...

What is the product for that you are welding?

I know a guy...that does something similar I think.

However IIRC it's weld overlaying on the end of a small valve stem,
so please send more details of your job, before I ring this guy up.

EDIT: googling your company names show similar work, so this may be your guy.
(or you already use him, and are not happy)
