What is the material of Hastelloy?


Hastelloy, nickel-based corrosion-resistant alloy; mainly divided into nickel-molybdenum alloy and nickel-chromium-molybdenum alloy. Use Hastelloy plates are suitable for a variety of chemical industries containing oxidizing and reducing media. The higher molybdenum and chromium contents make the alloy resistant to chloride ion corrosion, and the tungsten element further improves the corrosion resistance. At the same time, C-276 Hastelloy tube is one of only a few materials resistant to moisture chlorine, hypochlorite and chlorine dioxide. It has high concentration of chloride solution such as ferric chloride and copper chloride. Significant corrosion resistance. Application areas, heat exchangers, bellows compensators, chemical equipment, flue gas desulfurization and denitrification, paper industry, aerospace applications, acidic environments.


1 Excellent corrosion resistance for most corrosive media in both oxidizing and reducing atmospheres.

2 Excellent resistance to pitting, crevice corrosion and stress cracking corrosion.
