Key Features
Superior comprehensive corrosion resistance compared to other Ni-Cr-Mo alloys including Hastelloy C-276, C-4, and Inconel 625
Outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking
Excellent performance in oxidizing aqueous media including wet chlorine and nitric acid mixtures with chloride ions
Optimal resistance to environments with both reducing and oxidizing conditions
Exceptional resistance to strong oxidizers such as ferric and cupric chlorides, chlorine, and hot contaminated solutions
Resists formation of grain boundary precipitates in weld heat-affected zones
Suitable for use in as-welded condition for most chemical process applications
Applications
Chemical processing involving acetic acid, acetic anhydride, and complex acid mixtures
Pickling operations and cellophane manufacture
Chlorination systems and electro-galvanizing rolls
Expansion bellows and flue gas scrubber systems
