Alloy 601 is a nickel chromium alloy used for applications that require resistance to corrosion and heat. The composition is a face-centered-cubic solid solution with a high degree of metallurgical stability. It provides resistance to many corrosive media in high temperature environments. The oxidation resistance is further enhanced by the aluminum content. The alloy 601 develops a tightly adherent oxide scale which resists pitting and chloride stress corrosion cracking even under conditions of severe thermal cycling. This alloy has a good high temperature strength and retains its ductility after long service exposure.
