What are the characteristics of C276 Hastelloy?

C276 Hastelloy is widely used in chemical industry, petrochemical industry, flue gas desulfurization, pulp and paper making, environmental protection and other industrial fields because of its strong corrosion resistance.
 

What are the characteristics of C276 Hastelloy?

1. It has excellent corrosion resistance to most corrosive media in a redox atmoSPHEre.
2. It has excellent resistance to pitting, crevice corrosion and stress corrosion. The higher content of molybdenum and chromium makes Hastelloy alloy resistant to chloride ion corrosion, and tungsten element further improves corrosion resistance. At the same time, C276 Hastelloy is one of the only materials that can resist the corrosion of wet chlorine, hypochlorite and chlorine dioxide solutions, and has significant corrosion resistance to high concentration chloride salt solutions such as ferric chloride and copper chloride. It is suitable for sulfuric acid solutions of various concentrations and is one of the few materials that can be used for hot concentrated sulfuric acid solutions.
3. The mechanical properties of Hastelloy are very outstanding. It has the characteristics of high strength and toughness, difficult to process, and strong tendency of strain hardening. When the deformation rate reaches 15%, it is about twice that of 18-8 stainless steel. There is also a medium temperature sensitive area in Hastelloy, and its sensitization tendency increases with the increase of deformation rate. When the temperature is relatively high, Hastelloy easily absorbs harmful elements, reducing its mechanical properties and corrosion resistance.
