Incoloy 800/800H/800HT Pipe description
GNEE Incoloy 800/800H/800HT Pipe
Incoloy 800, 800H, and 800HT pipes belong to a series of high-performance nickel-iron-chromium alloys designed for strength, heat resistance, and corrosion resistance in extreme industrial environments. These grades-UNS N08800 (800), N08810 (800H), and N08811 (800HT)-are commonly used in applications requiring stable performance at high temperatures, such as heat exchangers, furnace components, petrochemical reformers, and power plant equipment.
Incoloy 800 pipes are known for their excellent resistance to oxidation, carburization, and sulfidation, making them ideal for medium-temperature range applications. Incoloy 800H, with its higher carbon content and controlled grain size, exhibits superior creep and stress rupture properties, enhancing its structural stability in high-temperature environments. Incoloy 800HT is the most advanced of the three alloys, offering even better stress rupture and creep resistance due to tighter control of aluminum and titanium content, making it suitable for the most demanding thermal corrosion environments.
Gnee Steel provides seamless alloy pipes conforming to standards such as ASTM B407 / ASME SB407 and serves critical industries including refining, power generation, chemical processing, and aerospace engineering. With comprehensive traceability, third-party certification, and global delivery capabilities, Gnee Steel's Incoloy 800/800H/800HT pipes have earned the trust of engineers, procurement managers, and original equipment manufacturers (OEMs) worldwide for their superior metallurgical properties and adherence to stringent international specifications.

FAQ
Q: What is the ASTM standard for Inconel 800?
A: Inconel 800 typically conforms to ASTM B407 standards for seamless tubes and ASTM B514 standards for welded tubes. These standards ensure that the alloy meets stringent requirements for quality, composition, and mechanical properties in high-temperature and corrosive applications.
Q: What is the maximum temperature for Inconel 800?
A: Inconel 800 alloy can operate effectively at temperatures up to approximately 1100°F (593°C). For applications involving higher temperatures, variant alloys such as Incoloy 800H and 800HT are generally preferred due to their enhanced creep resistance and thermal stability.
Q: What is the difference between Inconel 800 and 800H?
A: The main differences lie in the carbon content and grain size. Inconel 800H has a higher carbon content range (0.05%–0.10%) and controlled grain size, which gives it superior performance at high temperatures compared to standard Inconel 800.
