Hastelloy C22 (UNS N06022) Flange Manufacturer
Hastelloy® C22 flanges, made from UNS N06022 alloy, offer exceptional resistance to a wide range of aggressive chemical environments, including oxidizing and reducing agents. These high-performance flanges are commonly used in chemical processing, pollution control, marine, and pharmaceutical industries
Hastelloy C-22® alloy is a versatile nickel-chromium-molybdenum-tungsten alloy with better overall corrosion resistance than other Ni-Cr-Mo alloys available, including C-276 and C-4 alloys and alloy 625. C-22 alloy has exceptional resistance to a wide variety of chemical process environments, including strong oxidizers such as ferric and cupric chlorides, chlorine, hot contaminated solutions (organic and inorganic), formic and acetic acids, acetic anhydride, and seawater and brine solutions.
B462 C22 flange refers to a forged flange made from UNS N06022 (Hastelloy C-22) in accordance with the ASTM B462 standard.
