Hastelloy C276 widely used in the pulp and paper industry

Hastelloy C276 belongs to the nickel molybdenum chromium iron tungsten series nickel based alloy, which is the most corrosion-resistant modern metal material. It is mainly resistant to wet chlorine, various oxidizing chlorides, chloride salt solutions, sulfuric acid and oxidizing salts, and has good corrosion resistance in low and medium temperature hydrochloric acid. Therefore, in the past thirty years, it has been widely used in harsh corrosive environments such as chemical, petrochemical, flue gas desulfurization, pulp and paper, environmental protection and other industrial fields.

 

The various corrosion data of Hastelloy C276 have their typicality, but they cannot be used as specifications, especially in unknown environments, and must be tested before material selection. There is not enough Cr in Hastelloy C276 to resist corrosion in highly oxidizing environments, such as hot concentrated nitric acid. The production of this alloy is mainly aimed at the chemical process environment, especially in the presence of mixed acids, such as the discharge pipe of flue gas desulfurization systems.

 

The mechanical properties of Hastelloy alloy are very outstanding, with high strength and toughness, making it difficult to machine. When the deformation rate reaches 15%, it is about twice that of 18-8 stainless steel. Hastelloy also has a medium temperature sensitization zone, and its sensitization tendency increases with the increase of deformation rate. When the temperature is high, Hastelloy alloy is prone to absorbing harmful elements, resulting in a decrease in its mechanical properties and corrosion resistance.
