Alloy C-22 / Hastelloy C-22 / N06022 / 2.4602
The uniqueness and versatility of the alloy Inconel 22, Hastelloy C-22 is manifested in the fact that due to its composition - nickel-chromium-molybdenum-tungsten, it is endowed with high resistance to various corrosive formations, including crevice corrosion, local selective corrosion , and is not subject to stress corrosion cracking under high temperatures.
The high percentage of chromium in the composition is responsible for good resistance in oxidizing environments. Molybdenum and tungsten provide resistance to localized corrosion.
A- room temperature, like annealed.
Alloy 22 is not only characterized by resistance to oxidizing aqueous media, it exhibits high resistance to chlorine and nitric acid solutions, any acidic media with inclusions of chlorine ions.
In addition, Hastelloy C-22 is resistant to the effects of seawater (running and stagnant), chlorine anhydrides, acetic, sulfuric, hydrochloric and formic acids, and 2-valent copper. It is not susceptible to corrosion by direct contact with iron and copper chlorides, even with impurities of organic and inorganic substances when heated.
Due to its versatile qualities, Hastelloy C-22 is suitable for use in special areas when alloys of other groups cannot cope.
