Hastelloy C22 has good versatility and resistance to chloride-induced pitting HASTELLOY® C-22® alloy (UNS N06022) is a well-known nickel chromium-molybdenum materials, some main attributes are resistance to both oxidizing and non-oxidizing chemicals, protection from pitting, crevice attack, and stress corrosion cracking. C22 has a high chromium content that provides much higher resistance to oxidizing media than C-276 alloy.

Like other nickel alloys, HASTELLOY C-22 alloy is quite ductile, exhibits excellent weldability, and is fabricated easily into industrial components. It is available in the form of plates, sheets, strips, billets, bars, wires, pipes, and tubes. Typical applications might include: reactors, heat exchangers, and columns.
