ASTM B167 UNS N06600 (Inconel 600) Pipe
ASTM B167 UNS N06600 specifies seamless and welded pipes manufactured from high-performance nickel-chromium alloy Inconel 600. Known for its outstanding strength, oxidation resistance, and stability across elevated temperatures, Alloy 600 is widely used in chemical processing, heat-treatment systems, nuclear engineering, and furnace components. Its excellent resistance to chloride-ion stress corrosion cracking, carburization, and high-temperature oxidation makes it ideal for aggressive and thermal-cycling environments.
Key Features
- High temperature strength and oxidation resistance
- Excellent resistance to chloride stress corrosion cracking
- Non-magnetic with superior mechanical stability
- Good performance in carburizing and nitriding atmospheres
- Suitable for cryogenic to high-temperature applications
