COMMON TRADE NAMES: Hastelloy® C22
Alloy C22 is a nickel-chromium-molybdenum solid solution strengthened super-alloy with a nominal chemical composition of 56% nickel, 22% chromium, and 13% molybdenum, with additions of iron, tungsten, and cobalt. It is commonly referred to by the tradename Hastelloy® C22 and the universal designation UNS N06022. C22 has excellent corrosion and oxidation resistance, great mechanical properties over a wide range of temperatures, and good fabrication properties.
The exceptional corrosion resistance of C22 has promoted its use in many different markets wherever harsh environments are encountered, including the chemical process, pharmaceutical, food processing, oil & gas, power generation, and the paper industries. CRA offers specialty alloy C22 seamless pipe & tube for use in multiple industries and applications, including:
