Incoloy 800H pipe fittings elbows the metals or alloys such as steel and aluminum would succumb to thermal creep
Alloy 800H/800HT is frequently used in applications that involve long-term exposure to elevated temperatures where resistance to oxidation, carburization and other types of elevated temperature corrosion is required.
The nickel content makes the alloys highly resistant to both chloride stress-corrosion cracking and to embrittlement from precipitation of sigma phase. Alloy 800 series (Incoloy 800, 800H and 800HT) are nickel-iron-chromium superalloys that offer high temperature strength and resistance to oxidation, carburization and other types of high-temperature corrosion. Inconel and Incoloy are alloys that fall under the same family of superalloys and are often referred to as high performance.
