Welding 316L to 13Cr - Use 316L wire?
Welding 316L to 13Cr - Use 316L wire?
(OP)
We have a welding engineer advising us, but I have been asked to verify some of his work. He has reccomended using 309L wire to weld 316L to 13Cr, is this correct. The 309L wire does not have an Mo in it..

In some cases at the very borders, when welding, you will have aggregates of high carbon-low carbon and high cr-low cr and so on. since it segregates with heat. AND THEN it might not be "stainless" anymore in that region. But if this not actually required then options open up. :)
if welding a martensitic steel to an austenitic or ferritic is what you gotta do then you have to do it with 309 or 312 or similar. and obviouisly some things go out the window.

The other option is 310 filler.
You don't really have to worry about the corrosion resistance of the filler not being as good as 316, any of them will be a lot better than the 420.
