What is Hastelloy C22?

 

Hastelloy C22 Alloy 22 (UNS N06022; W. Nr. 2.4602; NiCr21Mo14W) is a fully austenitic advanced corrosion-resistant alloy that offers resistance to both aqueous corrosion and attack at elevated temperatures. This alloy provides exceptional resistance to general corrosion, pitting, crevice corrosion, intergranular attack, and stress corrosion cracking. Alloy 22 is nickel-base and typically contains 22% chromium, 14% molybdenum, and 3% tungsten. Iron is normally limited to less than 3%. The alloy's high content of chromium gives it good resistance to wet corrosion by oxidizing media.

Characteristics

· Excellent resistance to corrosion in stagnant or flowing seawater

· Good resistance to oxidizing aqueous media

· Outstanding resistance to both reducing and oxidizing media

· C22 excels in pitting resistance

· Excellent weldability

· Maximum expose temperature: 677°C / 1250°F

 

 

Applications

Hastelloy 22 has found numerous applications in the chemical/petrochemical processing, pollution control (flue gas desulfurization), power, marine, pulp and paper processing, and waste disposal industries. At elevated temperatures, the high chromium level of Hastelloy C-22 Alloy helps it resist oxidation, carburization, and sulfidation. Since it is nickel-base, alloy 22 resists high temperature attack by halides (e.g., chlorides and fluorides). With these attributes, the alloy is widely used to protect steel tubes and other components in coal-fired and waste-to-energy boilers.

 Such as the fields of

·Chemical Processing

·Chlorination systems

·Food Processing

·Pharmaceutical industry

·Oil & Gas

·Power Generation

·Pulp & Paper Industries

·Acetic acid production

·Fine chemicals

Corrosion Resistance in the As-Welded Condition

Hastelloy C-22 is a versatile nickel-chromium-molybdenum alloy with better overall corrosion resistance than other Ni-Cr-Mo alloys available today, including hastelloy C-276, C-4, and A625. Alloy C-22 has outstanding resistance to pitting, crevice corrosion and stress-corrosion cracking. It has excellent resistance to oxidizing aqueous media including acids with oxidizing agents, wet chlorine and mixtures containing nitric acid or oxidizing acids with chlorine ions. Hastelloy C-22 has outstanding resistance to both reducing and oxidizing media, and because of its versatility can be used where "upset" conditions are likely to occur or in multipurpose plants.

Hastelloy C-22 has exceptional resistance to a wide variety of chemical process environments, including strong oxidizers such as ferric and cupric chlorides, hot contaminated media (organic and inorganic), chlorine, formic and acetic acids, acetic anhydride, and seawater amd brine solutions.

Hastelloy C-22 resists the formation of grain boundary precipitates in the weld heat affected zone, thus making it suitable for most chemical process applications in the as-welded condition.
