Incoloy 800HT Raised Face Flanges

Incoloy 800/800H/800HT Flanges are made from nickel-iron-chromium alloys, typically containing 30–35% nickel, 19–23% chromium, and a balance of iron, along with carefully controlled amounts of carbon, aluminum, and titanium. The 800H and 800HT versions have higher carbon content and optimized aluminum/titanium levels to enhance creep and stress rupture properties. These flanges provide tensile strengths ranging from 500–700 MPa and show remarkable resistance to oxidation, carburization, and sulfidation. Their mechanical integrity under prolonged exposure to temperatures exceeding 600°C makes them ideal for high-heat environments and aggressive chemical conditions.

Incoloy 800, 800H, and 800HT Flanges are widely utilized in heat exchangers, boilers, furnace retorts, reformer outlets, superheaters, and nuclear steam generators due to their impressive high-temperature and oxidation resistance. These flanges are particularly suited for chemical plants, power stations, and petrochemical refineries, where components face thermal cycling and corrosive environments. Their ability to resist carburization and stress-related corrosion makes them a great choice for steam cracking, ammonia reforming, and other demanding applications.
