ASTM B690 Alloy 8367 Nickel Chromium Molybdenum Alloy Seamless Pipe

The ASTM B690 specification covers seamless pipes and tubes made from Nickel-Chromium-Molybdenum Alloy 8367, which are designed for use in environments requiring exceptional corrosion resistance and high mechanical strength. This alloy is specifically engineered to withstand harsh operating conditions, including exposure to oxidizing and reducing agents, as well as environments with chloride-induced stress corrosion cracking.

Key Features:

• Material Composition:

  • Contains nickel (Ni) as the primary component, with significant amounts of chromium (Cr) and molybdenum (Mo).
  • The combination provides excellent strength, toughness, and superior resistance to pitting and crevice corrosion.

• Corrosion Resistance:

  • Ideal for applications in chemical processing, marine environments, and offshore industries.
  • Offers resistance to a wide range of aggressive chemicals, including acids and alkalis.

• Mechanical Performance:

  • High tensile and yield strength, suitable for high-temperature and high-pressure environments.
  • Good ductility and toughness ensure reliable performance under extreme conditions.

• Seamless Construction:

  • Manufactured using advanced methods to ensure uniformity, precise dimensional tolerances, and leak-proof performance.
  • Seamless pipes are free from welds, making them more reliable in critical applications.
