Incoloy alloys belong to the Inconel family. This means that the alloy can be used at high temperatures. At high temperatures, a problem associated with certain grades of stainless steel is oxidation. The chemical composition of Incoloy 800 fasteners allows them to be used at high temperatures. The higher the carbon content, the more chance they have to withstand high temperatures. Therefore, manufacturers produce derivative alloys of UNS N08800 bolts, called Alloy 800H and Alloy 800HT, which have slightly different chemical compositions.
