Hastelloy C-22 Stud Bolt UNS N06022 Hex Bolt Nuts

China professional manufacturer of Hastelloy C-22 Stud Bolt UNS N06022 Hex Bolt Nuts in China.

HASTELLOY Alloy C-22 is a nickel-chromium-molybdenum alloy with enhanced resistance to pitting, crevice corrosion and stress corrosion cracking.

A HASTELLOY C-22 stud bolt is a fastener made from this alloy, offering superior performance in applications that involve harsh chemical environments, high temperatures, and corrosive substances. These stud bolts are commonly used in industries such as chemical processing, petrochemical, pharmaceuticals, and marine environments.

Applications of HASTELLOY Alloy C-22 Stud Bolt

HASTELLOY C-22 stud bolts are widely used in industries and applications where resistance to corrosion and high temperatures is critical. Some of the key applications include:

  1. Chemical Processing:
    • reactors, heat exchangers, and piping systems
    • Particularly useful in environments involving sulfuric acid, phosphoric acid, and other corrosive substances.
  2. Petrochemical Industry:
    • In refinery units, reactors, and distillation columns that handle aggressive chemicals and high-temperature processes.
  3. Pharmaceutical Manufacturing:
    • Used in equipment where the material must resist corrosion while ensuring the integrity of the system, especially when exposed to harsh sterilization processes or acidic substances.
  4. Marine and Offshore Applications:
    • Ideal for components exposed to seawater or marine environments, where chloride corrosion is a significant concern.
  5. Pulp and Paper Industry:
    • Used in paper mill equipment where the alloy is exposed to harsh bleaching and pulping processes.
  6. Aerospace and High-Performance Systems:
    • For parts and equipment exposed to high temperatures and corrosive agents.
