Incoloy 800HT Elbows required for high surface stability
These nickel steel alloys are identical except for the higher level of carbon in alloy 800H, and the addition of up to 1.20 percent aluminum and titanium in alloy 800HT. Incoloy 800 was the first of these alloys and it was slightly modified into Incoloy 800H.
To ensure the best high temperature properties, Incoloy 800 H has additional titanium and aluminium modifications (0.85 to 1.2 percent). Dual certified, the alloy combines the properties of the two forms. The chemical balance of the alloy enables it to resist carburization, oxidation, and nitriding atmospheres exceptionally well. 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. The nickel content makes the alloys highly resistant to both chloride stress-corrosion cracking and to embrittlement from precipitation of sigma phase. Alloy 800 is a variation of Inconel superalloys. These are super austenitic stainless steel materials. There are silicon, molybdenum, copper, nitrogen and other elements in addition to the chromium, nickel iron base of the alloy. They are very much corrosion resistant under various environments and exhibit high strength under high temperatures.
