Incoloy 800, 800H, and 800HT pipes are nickel-iron-chromium alloys designed for high-temperature applications requiring strength and resistance to oxidation and carburization. While similar in composition, they differ in carbon, titanium, and aluminum content. Incoloy 800, the original alloy, was modified to create 800H by controlling carbon content (0.05%-0.10%) and grain size for improved stress rupture properties. Incoloy 800HT further enhances high-temperature performance with additions of titanium and aluminum (0.85%-1.20%).
We offer Incoloy 800 pipes and tubes in standards specifications at the most competitive prices. For more information on our Inconel Pipes & Tubes, feel free to contact us. Let us help you find the perfect solution for your industrial needs.
