What Is The Difference Between Hastelloy C276 And C22?

1. Composition:

Hastelloy C276:

Nickel (Ni): 57%

Chromium (Cr): 14.5-16%

Molybdenum (Mo): 15-17%

Iron (Fe): Balance

Tungsten (W): 3-4.5%

Hastelloy C22:

Nickel (Ni): 56%

Chromium (Cr): 20-22%

Molybdenum (Mo): 12-14%

Iron (Fe): Balance

Tungsten (W): None

2. Corrosion Resistance:

Hastelloy C276:

Excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, especially in reducing environments.

Particularly effective in sulfuric and hydrochloric acids.

Hastelloy C22:

Superior resistance to both oxidizing and reducing environments, making it more versatile.

Better resistance to pitting and crevice corrosion in chloride-containing environments compared to C276.

3. Mechanical Properties

Hastelloy C276:

Known for its high strength and toughness at elevated temperatures.

Hastelloy C22:

Offers good mechanical strength and ductility, with enhanced performance in corrosive environments.

4. Applications

Hastelloy C276:

Commonly used in chemical processing, oil and gas, and pollution control applications where resistance to harsh chemicals is critical.

Hastelloy C22:

Frequently used in pharmaceutical, food processing, and marine applications due to its versatility in different environmental conditions.

5. Weldability

Both alloys are highly weldable; however, Hastelloy C22 may offer slightly better performance in welding applications due to its lower sensitivity to hot cracking.

Summary

Hastelloy C276 is often preferred for applications involving severe reducing conditions.

Hastelloy C22 is favored for environments that are both oxidizing and reducing, offering broader corrosion resistance. The choice between the two depends on the specific requirements of the application, including the types of corrosive environments and mechanical properties needed.
