INCOLOY nickel-iron-chromium alloy 800 was introduced to the market in the 1950s to fill the need for a heat- and corrosion-resistant alloy with a relatively low nickel content since nickel was, at the time, designated a “strategic” metal. Over the past forty years it has been widely used for its strength at high temperatures and its ability to resist oxidation, carburization, and other types of high-temperature corrosion. Applications include furnace components and equipment, petrochemical furnace cracker tubes, pigtails and headers, and sheathing for electrical heating elements.

INCOLOY alloy 800 has high mechanical strength over a broad temperature range. In general, alloy 800 is used for its strength characteristics at service temperatures up to about 1500°F (816°C). At those temperatures, equipment design is usually based on tensile properties. For applications that require high creep or rupture strength, INCOLOY alloys 800H and 800HT are used.
INCOLOY alloy 800 exhibits high tensile properties at room and elevated temperatures. Figures 2 and 3 show tensile properties at temperatures to 1500°F (815°C) of hot-rolled rod in the as-rolled and the annealed conditions. Tensile properties at room temperature and from 1200°F (650°C) to 1800°F (980°C) of as-extruded tubing are given in Table 6.

Cold work substantially increases the tensile properties of the alloy. Properties of cold-drawn rod in the as-drawn condition are given in Table 7.
High-temperature hardness and tensile properties of annealed and hot-rolled material are shown in Table 8.
