Alloy 800 series (Incoloy 800, 800H and 800HT) are nickel-iron-chromium superalloys that offer high temperature strength and resistance to oxidation, carburization and other types of high-temperature corrosion. Alloy 800 (UNS N08800), Alloy 800H (UNS N08810) and Alloy 800AT (UNS N08811) have the same content of Nickel, Chromium and iron, what makes the difference is the combined titanium and aluminum levels (0.85 to 1.2%) to ensure optimum high temperature properties.
LKALLOY mainly stocks and produces Alloy 800 plate, Alloy 800 pipe, Alloy 800 bar and other forms in various size and specifications. They are mainly used in various applications from furnace components, petrochemical furnace cracker tubes to sheathing for electrical heating elements.
