“…Both phenomena cause a drop in toughness and an increased cold cracking sensitivity in the welded joint. The literature on duplex stainless steels is rather comprehensive (see supplementary literature 19,168,170,244,247,248,380,381,382,383,384,385,386,387,388,389,463,464,465,466,467,477,478). This situation has led to the development of austenitic-ferritic Cr-Ni-Mo alloyed duplex steels with low carbon contents and quite often alloyed with nitrogen.…”
