Hastelloy C-22: A Versatile Corrosion-Resistant Alloy for Extreme Environments

Hastelloy C-22, also known as Alloy C-22 or UNS N06022, is a high-performance nickel-chromium-molybdenum alloy designed to withstand highly corrosive environments. Its exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking makes it an ideal choice for industries requiring durability and reliability in extreme conditions.

Applications of Hastelloy C-22

Hastelloy C-22 is widely used in various industries, including:

  • Chemical Processing Equipment: Provides resistance to oxidizing and reducing environments.

  • Flue Gas Desulfurization Systems: Ensures longevity in acidic environments.

  • Pharmaceutical Manufacturing: Maintains purity and resists contamination.

  • Pulp and Paper Industry: Protects against corrosive chemicals used in production.

  • Marine Engineering: Offers superior performance in saltwater and harsh marine conditions.

  • Waste Treatment Facilities: Withstands exposure to aggressive chemicals and high temperatures.


Key Properties of Hastelloy C-22

  • Pitting Corrosion Resistance: Effectively combats localized corrosion in chloride-containing environments.

  • Crevice Corrosion Resistance: Prevents degradation in tight spaces where corrosive agents accumulate.

  • Stress Corrosion Cracking Resistance: Maintains structural integrity under stress and heat.

  • High-Temperature Stability: Performs well in temperatures up to 1250°F (677°C).

  • Excellent Weldability: Easily fabricated using conventional welding techniques.


Hastelloy C-22 Forms and Specifications

Hastelloy C-22 is available in various forms, including Hastelloy C-22 pipe, Hastelloy C-22 tube, ASTM B575 Hastelloy C-22, ASME SB575 Hastelloy C-22, and more. It conforms to international standards such as DIN 2.4602, ISO 6208, ASTM B574, DIN 17753, and ASME SB 906.

Hastelloy C-22 vs. Other Nickel Alloys
