Hastelloy C22 - A Versatile Alloy

Hastelloy C22 is also called alloy C22, and happens to be a versatile austenitic nickel-chromium-molybdenum-tungsten alloy with improved resistance to stress corrosion cracking, pitting and crevice corrosion. Its high chromium content offers good resistance to oxidizing media while the tungsten and molybdenum content provide good resistance to decreasing media. Supreme Engineering Limited Hastelloy C22 suppliers and Hastelloy C22 manufacturers can be contacted for further details.

This is a nickel steel alloy that also boasts of profound resistance to oxidizing aqueous media that includes wet chlorine and mixtures that consist of nitric acid or oxidizing acids with chlorine ions. Hastelloy C22 also has resistance to corrosives like oxidizing acid chlorides, formic and acetic acids, wet chlorine, cupric and ferric chlorides, brine, sea water and other mixed or contaminated solutions.

Features of Hastelloy C22:

  • Great resistance to reducing and oxidizing media.
  • Resistant to stress corrosion cracking, pitting and crevice corrosion.
  • Good resistance to oxidizing aqueous media.
