The new NiCr20Fe14Mo11WN filler metal is characterized by exceptional resistance to pitting and crevice corrosion, no sensitiveness to chloride induced stress corrosion cracking and shows excellent mechanical 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 duplex steels is possible, which proves the alloy to be superior to alloy 625.
