Incoloy 800H steel sheet is a high temperature version of the Incoloy 800 alloy, which is an iron-nickel-chromium-based austenitic superalloy. Its excellent balance of high temperature strength, corrosion resistance, and oxidation resistance makes it an indispensable key material in the petrochemical, heat treatment, and power industries.

astm incoloy 800h plate High temperature strength and creep resistance
Incoloy 800H steel sheet, through the combined effects of solid solution strengthening (Ni, Cr) and second-phase precipitation strengthening (TiC, etc.), exhibits significantly higher creep rupture strength than ordinary stainless steels (such as 304H, 310S) within the temperature range of 600°C to 1100°C. This allows equipment made from 800H plate to be designed thinner and lighter, or to operate safely at higher temperatures and pressures.

Oxidation: The surface Cr₂O₃ film is extremely stable in high-temperature air and can effectively resist continuous oxidative peeling.
Carburization: In an atmosphere rich in hydrocarbons such as carbon monoxide and methane (such as a petrochemical cracking furnace), carbon can penetrate the surface of the metal, forming carbides, which can lead to material embrittlement, expansion, and ultimately cracking. The high nickel content of Incoloy 800H can effectively inhibit the penetration and diffusion of carbon, protecting the internal structure of the material.

alloy 800h plate corrosion resistance
- Incoloy 800H steel sheet has excellent corrosion resistance to various aqueous media (including fresh water and seawater) and atmospheric environments.
- It can resist corrosion from various acid, alkali and salt solutions, and is particularly stable in complex environments with alternating reducing and oxidizing conditions.
- Resistance to chloride stress corrosion cracking (Cl-SCC) is superior to 304/316 stainless steel.
incoloy 800h hot rolled plate processing and welding performance
Sheet processing: Incoloy 800H steel sheet has good cold and hot formability, and can be cut, bent, stamped, and spun. However, due to its high strength and high work hardening rate, it requires greater processing force than ordinary stainless steel and may require intermediate annealing treatment.
Welding: Common arc welding methods such as TIG, MIG, and SMAW can be used for welding. Incoloy 800H steel sheet is recommended to use compatible welding materials such as Inconel 625 or AWS ERNiCr-3 welding wire to obtain optimal weld performance and crack resistance. To ensure post-weld performance, especially corrosion resistance, post-weld solution treatment is usually required.
Application of alloy n08810 sheet
Oil and gas: submarine pipelines, downhole tools for acid gas wells.
Chemical equipment: sulfuric acid reactors, phosphoric acid evaporators, pickling equipment.
Nuclear industry: containers and pipelines for nuclear waste treatment systems.
Marine engineering: seawater desalination devices, heat exchangers.
Environmental protection: key components of flue gas desulfurization (FGD) systems.
