Thank you for all your posts. The Schaeffler diagram was a big help once I figured out how to account for dilution of both base metals. Based on the prediction of the final weldment, I don't believe there is a martensitic micro structure, but the ferrite percentage is low enough to be a concern...
Thanks for the information Stan. Maybe it would help me if we start with another question. What properties does the 309 fillerr have that make it the preferred choice for dissimilar welds? My understanding is that when joining dissimilar metal you need an over alloyed filler, at least for cs to...
I currently have a project where we are welding 304 ss and 316 ss to carbon steel. This is a lower temp application so I specified a WPS with 309 filler. After PMI on several of the weld it was discovered the wire was marked 309 but was actually 316 ss. What potential problems do I have with...
