| Abstract: | The Nb‐free NiCr20Fe14Mo11WN alloy has been developed as a new filler metal which combines high strength and excellent corrosion resistance in wet environments at ambient temperatures. The alloy is characterized by exceptional resistance to pitting and crevice corrosion, no sensitiveness to chloride induced stress corrosion cracking and shows high mechanical properties, e.g. 0.2 %‐yield strength. Because the alloy is practically free of stable nitride formers like niobium, titanium etc., no nitride formation during welding of super austenitic, duplex and super duplex steels is possible, which proves the alloy to be superior to alloy 625. |
