The new NiCr20Fe14Mol 1WN filler metal is characterized by exceptional resistance to pitting and crevice corrosion, no sensitiveness to chloride induced stress corrosion cracking and shows excellent me-
chanical properties, e.g. 0.2 %-yield strength. Because the alloy is practically free of stable nitride formes like niobium and titanium, no nitride formation during welding of super austenitic, duplex and super du-
plex steels is possible, which proves the alloy to be superior to alloy 625.
