Hastelloy C22

C22 is among the most universally corrosion-resistant alloys available. The combination of 22% chromium, 13% molybdenum and 3% tungsten gives it resistance in both oxidising and reducing conditions — unusual, and the reason it is specified where the process chemistry is mixed, upset-prone or not fully characterised. It resists pitting, crevice attack and stress corrosion cracking in aggressive chloride service.

Here are some key aspects of Hastelloy C22:

Composition:

  • Nickel (Ni): The primary component, which gives the alloy its excellent resistance to corrosion and oxidation.
  • Chromium (Cr): Enhances resistance to oxidizing media.
  • Molybdenum (Mo): Contributes to resistance against reducing environments.
  • Tungsten (W): Adds to the overall strength and stability of the alloy.

Corrosion Resistance:

  • Hastelloy C22 is highly resistant to pitting, crevice corrosion, and stress corrosion cracking.
  • It can withstand both oxidizing and reducing environments, making it suitable for handling a variety of chemicals.

Applications:

  • Chemical Processing: Used in equipment and components that handle harsh chemicals, including acid production and processing, chemical reactors, and pollution control equipment.
  • Aerospace: Employed in the manufacture of components exposed to extreme environments.
  • Marine Engineering: Utilized in marine applications where exposure to seawater and salt spray can cause severe corrosion.

Mechanical Properties:

  • High strength and toughness over a wide range of temperatures.
  • Good weldability and formability, allowing it to be shaped into various components and structures.

Standards and Specifications:

  • Hastelloy C22 is often produced according to standards set by ASTM (American Society for Testing and Materials), ASME (American Society of Mechanical Engineers), and other international bodies.

Comparison to Other Alloys:

  • Compared to other Hastelloy grades, such as C276, C22 offers superior resistance to oxidizing environments.
  • It is also preferred over other nickel-based alloys when both reducing and oxidizing conditions are present in the application environment.

FAQ

04

Selecting a grade

What is the difference between 304 and 316?
316 contains 2 to 3 percent molybdenum, which 304 does not. That improves resistance to pitting and crevice corrosion in chloride environments, which is why 316 suits marine, chemical and coastal service. For dry indoor, food and general water use, 304 performs well at lower cost.
What is duplex and super duplex stainless steel?
A duplex microstructure is roughly half austenite and half ferrite, giving about double the yield strength of 316L together with much better resistance to chloride stress corrosion cracking. Super duplex (for example 2507) pushes corrosion resistance further for seawater and sour service. The main limit is a maximum service temperature near 300 degrees Celsius.
What does PREN mean?
PREN is the Pitting Resistance Equivalent Number: percent chromium plus 3.3 times percent molybdenum plus 16 times percent nitrogen. Higher means better resistance to pitting in chlorides. It is a ranking figure, not a substitute for assessing a specific service condition.
Which grade should I choose?
It depends on the medium, temperature and pressure the material will see. Our grade pages and the grade comparator set out composition, corrosion behaviour and limitations side by side; if you tell us the service conditions, we will tell you what we would specify.
