Alloy 800H and 800HT (commonly referred to as Alloy 800T series) are high-temperature strength variants of Incoloy 800, engineered to perform in extreme thermal and oxidizing environments. These iron-nickel-chromium alloys are commonly used in petrochemical processing, heat exchangers, power plants, and industrial furnaces. The price per kilogram of Alloy 800H/800HT sheet in 2025 is driven by alloy composition, sheet thickness, global nickel pricing, and required certifications such as ASTM B409 or ASME SB-409. This article explores the current price ranges, application sectors, and regional differences to guide bulk buyers and engineers.
