What is ASTM / ASME UNS N06022?
ASTM / ASME UNS N06022 or W. Nr. 2.4602 (NiCr21Mo14W) is a nickel based superalloy that was specifically designed to provide the best in long term reliability and extreme corrosion resistance. This superalloy contains large amounts of nickel, chromium, molybdenum, and tungsten thus giving it excellent protection against reducing and oxidizing chemicals.
UNS N06022 Fasteners outperform traditional stainless steels and nickel alloys in environments that contain mixed chemicals as well as solutions of phosphoric acid, hydrochloric acid, sulfuric acid, and chlorides.
This is why Inconel Alloy 622 fasteners are selected worldwide for important projects where equipment must be safe and reliable.
