What is your specific application, including service temperature?

You can find some general information in Section II-C to help point you in the right direction.

RE: Dissimilar metals
One point that I want to add to the excellent posts above is this, your combination of joining cast 2.25 Cr-1 Mo (SA- 217 WC9) to 410ss can be complicated because of the hardenability of 410 ss. I would recommend that you seek advice from a welding or metallurgical engineer concerning selection of a suitable filler metal and weld joint design. This is the reason for my asking what is your specific application. If the preheat and PWHT parameters along with the selection of filler metal are not carefully evaluated, you can have a serious problem.
