Hee,
Typically ferrite count is driven by code or client requirements, none of which you have listed in your post. Also, it usually is a concern with filler metal. Need more information.

ASME code, check on HAZ once weld completed. Required from our client.

"ASME code" Doesn't really narrow it down much. If required by client then they should be giving you some kind of values that are acceptable. Correct?

Yes, you are right. Thanks
