Incoloy 800/800H/800HT Sheets and Plates

Incoloy 800, 800H, and 800HT sheets and plates are top-notch nickel-iron-chromium alloys designed to deliver impressive strength and resistance to oxidation, especially in high-temperature settings. You’ll often find these materials in industries like thermal processing, petrochemicals, and power generation, thanks to their remarkable stability and ability to withstand carburization and oxidation even when the heat is on. While all three grades share a similar base composition, 800H and 800HT are enhanced versions that provide better creep and stress rupture strength, making them perfect for those tougher, high-heat applications.

When it comes to their chemical makeup, you’re looking at around 30–35% nickel and 19–23% chromium, along with carefully controlled amounts of aluminum and titanium. Incoloy 800H stands out with a higher carbon content (0.05–0.10%) to boost strength at elevated temperatures, while 800HT takes it a step further with tighter controls on aluminum and titanium for even better performance under prolonged heat exposure. These alloys keep their excellent mechanical properties up to 1100°C, boasting tensile strength between 450–600 MPa and good ductility. Plus, all grades are known for their great weldability and formability, making them ideal for both intricate and heavy-duty fabrication tasks.
