Hastelloy C22 Pipe Fittings – UNS N06022

Hastelloy C22 Pipe Fittings are critical piping components, such as elbows, tees, and reducers, fabricated from a versatile nickel-chromium-molybdenum-tungsten alloy (UNS N06022). These fittings are specially designed to facilitate changes in pipeline direction, size, or branching, all while maintaining the integrity of the fluid transport system in the face of highly aggressive environments. Their complex chemical composition provides outstanding immunity to localized corrosion, stress-corrosion cracking, and general corrosion in both oxidizing and reducing media, making them superior to standard stainless steels. Zeron Fastners is a reliable manufacturer and supplier of Hastelloy C22 pipe fittings, meeting rigorous dimensional standards for essential applications in the chemical processing, pharmaceutical, and pollution control industries.
