Engineering reference, not a mill test report. Actual chemistry, properties, condition, availability and qualification must meet the ordered product specification and accompanying certification.

Material Properties, Typical Parts and Selection

C-22 and C-276 are distinct UNS grades with different chemistry and corrosion characteristics. Representative applications include valve shafts, chemical-process fittings and specialized corrosive-service components. Suitability depends on the environment, grade, geometry, strength/temper and processing route. Specify finished-size and material performance separately; two alloys with similar commercial names may have different test standards.

Precision Grinding, Straightening and Bar Finishing

Mozaic Precision Metals supports project-specific bar sourcing and centerless grinding, straightening, polishing, cutting, chamfering and packaging. Describe the incoming and finished OD, bar length, drawing requirements, production quantity and material traceability. Surface roughness, diameter tolerance and straightness are independent acceptance characteristics, and actual capability is confirmed by quote.

What is Hastelloy C22?

Hastelloy C22 is a nickel-based superalloy engineered for exceptional corrosion resistance and performance under extreme temperatures. Part of the Hastelloy family, this alloy was developed as an improvement over Hastelloy C276, offering enhanced protection against localized corrosion and improved stability in highly aggressive environments.

Chemical Composition of Hastelloy C22

Hastelloy C22 is primarily composed of nickel, molybdenum, and chromium, with smaller amounts of tungsten, iron, and cobalt. Trace elements such as carbon, silicon, and manganese provide additional strength and stability. This unique chemistry allows the alloy to resist both oxidizing and reducing agents, making it one of the most versatile corrosion-resistant materials available.

Key Benefits of Hastelloy C22

  • Exceptional Corrosion Resistance: Protects against strong oxidizers, reducing agents, chlorides, and sulfuric acid.
  • High-Temperature Performance: Maintains mechanical integrity under extreme heat and pressure.
  • Versatility: Performs reliably across a wide range of chemical and industrial environments.

Applications of Hastelloy C22

Hastelloy C22 is widely used in industries where reliability in aggressive conditions is critical. Common applications include:

  • Chemical processing equipment and reactors
  • Pollution control and flue gas scrubbers
  • Pulp and paper bleaching systems
  • Aerospace components exposed to corrosive conditions
  • Marine and offshore engineering
