Incoloy 800H pipe fittings elbows well suited to marine applications
Both materials remain available, subject to commercial considerations, and certain specifications which restrict the service temperature of some grades of INCOLOY alloy 800H.
The nickel alloy is dual certified (800H/HT) and combines the properties of both forms. Incoloy 800H/HT alloy was intended for high temperature structural applications. It has almost the same chemical composition as Alloy 800 except that it requires a higher carbon addition resulting in improved high-temperature properties. 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.
