The Hastelloy C22 Flanges are made from a combination between Nickel and Chromium with additions of Molybdenum and tungsten. They are designed to offer excellent resistivity against stress corrosion cracking and crevice corrosion. The combination of Chromium and molybdenum helps these flanges to have high resistivity against both oxidizing media and reducing media. The Optimum resistivity of the Hastelloy C22 Flanges against environments that encounter process streams of reducing and oxidizing conditions is beneficial in the multi-purpose industries where such conditions occur frequently. They also offer excellent forming characteristics; therefore, they are suitable for manufacturing various types of Flange faces.
The Hastelloy C22 Flanges offer excellent resistivity against both reducing and oxidizing media including wet chlorine and mixtures containing nitric acid or oxidizing acids with chlorine ions. They also offer high resistivity against formic and acetic acids, oxidizing ac
