Welded product and ferrite-austenite stainless steel welding processes

A welded article comprises first and second parts welded together such that the parts are joined by a weld, the first and second parts being formed from the same or different austenitic stainless steels, wherein the weld has a Cr-equivalent/Ni-equivalent ratio, R, of about 1.5 to 2.0, wherein Cr equ...

Beschreibung
Zusammenfassung:	A welded article comprises first and second parts welded together such that the parts are joined by a weld, the first and second parts being formed from the same or different austenitic stainless steels, wherein the weld has a Cr-equivalent/Ni-equivalent ratio, R, of about 1.5 to 2.0, wherein Cr equivalent = Cr + 1.37 Mo + 1.45 Si + 2 Nb + 3 Ti, and Ni equivalent = Ni + 0.31 Mn + 22C + 14.2 N + Cu.
