Hi Guys,
Can someone explain to me why SFA-5.39 (Specification for Flux and Electrode Combinations for Submerged Arc and Electroslag Joining and Surfacing of Stainless Steel and Nickel Alloys) does not require a diffusible hydrogen designator like SFA-5.17 does for Carbon Steel SAW.
We are welding some 316 SS spools and our customer is insisting that the wire/flux combination should have maximum diffusible hydrogen content of H4 or better.
I have tried telling him that SFA-5.39 does not require a diffusible hydrogen test. I have also told him that the specification for the hydrogen test, AWS A4.3, does not include testing for Austenitic SS.
Is there anything else that I can tell or show him that I will not be able to get a 3.1 certificate showing hydrogen levels?
Thanks
