Incoloy 800 Alloy developed to work in high temperatures.

Incoloy 800 is an austenitic, solid-solution alloy. Titanium nitrides, titanium carbides, and chromium carbides normally appear in the alloy’s microstructure. The nitrides are stable at all temperatures below the melting point and are therefore unaffected by heat treatment. Chromium carbides precipitate in the alloy at temperatures between 1000 and 2000°F (540 and 1095°C). Consequently, UNS N08800 alloy is similar to other austenitic alloys in that it can be rendered susceptible to intergranular corrosion (sensitized) in certain aggressive environments by exposure to temperatures of 1000 to 1400°F (540-760°C). An important property of Alloy 800 is its relative freedom from chloride stress-corrosion cracking. Extensive studies of stress-corrosion cracking of austenitic alloys in chloride solutions have shown that the tendency to crack decreases with increasing nickel content of alloy. For example, Inconel 600, with a nickel content of 76%, is considered to be immune to chloride-ion stress-corrosion cracking. Incoloy 800 (32.5% Ni) can be made to crack in severe laboratory tests, but it has such high resistance that it is commonly used to replace materials that have failed in service from stress-corrosion cracking.
