Welcome to Golden Steel Material Let’s Talk
Incoloy 800H (UNS N08810) Plates, produced under the ASTM B409 specification, represent a specialized high-carbon version of the standard Incoloy 800 alloy. While it shares the same base nickel-iron-chromium chemistry, Alloy 800H is precision-engineered with a controlled carbon content (0.05% to 0.10%) and is subjected to a high-temperature solution annealing process. This specific heat treatment ensures a coarse grain structure, which is the defining factor in providing significantly higher creep and stress-rupture strength. These plates are the industry standard for structural applications where the material must withstand prolonged mechanical stress at temperatures exceeding 600°C (1100°F).
The technical superiority of ASTM B409 Incoloy 800H is particularly evident in the petrochemical and power generation sectors. Because it maintains its structural integrity and resists embrittlement during long-term thermal exposure, it is the premier choice for ethylene furnace pigtails, steam-methane reformer headers, and power plant superheater tubing. Beyond its mechanical endurance, the alloy provides excellent resistance to oxidation, carburization, and nitriding, forming a robust barrier against environmental degradation. For engineers designing pressure vessels, heat exchangers, and thermal processing equipment, Incoloy 800H plates offer the ideal combination of metallurgical stability and high-temperature performance required for safety-critical industrial operations.
