Incoloy 800HT Plate for High-Temperature Durability in Furnaces and Reactors
Our Incoloy 800H T plate is built to deliver top-notch durability in the scorching conditions of furnaces and reactors, keeping critical components like radiant tubes and heat exchangers running strong. This isn’t just metal—it’s a rugged solution for industries tackling extreme heat and stress. Let’s dive into what makes our Incoloy 800HT plate a standout, from its tough materials to its key applications, while exploring industry trends and why our company is the go-to for high-temperature reliability.
We craft our Incoloy 800HT plate from a high-performance alloy of 30-35% nickel, 19-23% chromium, iron, with a higher carbon content (0.06-0.10%) and increased aluminum and titanium for superior creep strength. The nickel and chromium form a stable oxide layer that fights oxidation and carburization up to 1500°F (816°C), while the elevated carbon and Al/Ti additions boost creep and rupture strength for long-term performance under thermal stress. Available in thicknesses from 0.1875″ (4.8mm) to 2.00″ (50.8mm), it’s designed for easy forming and welding, meeting standards like ASTM B409 and ASME SB 409. Our rigorous testing ensures purity and consistency, delivering plates that resist scaling, creep, and thermal fatigue, lasting 3-5 years in demanding furnace and reactor environments. This makes it perfect for petrochemical, power generation, and industrial furnace applications.
