Incoloy 800H｜Alloy 800H｜N08810｜Pipe and Tube
Incoloy 800H (Alloy 800H,UNS N08810) is an iron-nickel-chromium alloy having the same basic composition as Incoloy 800, with significantly higher creep rupture strength. The higher strength results from close control of carbon, aluminum and titanium contents in conjunction with a high temp anneal. Incoloy 800 H has further modifications to the combined titanium and aluminum levels (0.85 to 1.2%) to ensure optimum high temperature properties.
The alloy is dual certified and combines the properties of both forms. The chemical balance allows the alloy to exhibit excellent resistance to carburization, oxidation and nitriding atmospheres. 800HT will not become embrittled even after long periods of usage in the 1200-1600 deg F range where many stainless steels become brittle. Typical applications for the alloy include ethylene pyrolysis, hydrocarbon cracking, cracking furnaces for vinyl chloride, diphenol and acetic acid. The alloy is also used for valves, fittings and other components exposed to corrosive attack from 1100 to 1800 deg F.

5. Applications of Incoloy 800H
Alloy 800H is frequently used in applications that involve long-term exposure to elevated temperatures where resistance to oxidation, carburization and other types of elevated temperature corrosion is required. Heat treatment and power generation are two common industries where alloy 800H is used. Typical applications include superheater and reheater tubing, headers, pigtails, outlet manifolds and sheathing for heating elements.
