Incoloy 800HT Elbows with Excellent resistance to oxidation

Alloy 800HT / Incoloy 800HT is a controlled composition derivative of INCOLOY? alloy 800H (UNS N08810) and is used for the same creep resistant applications, however the combined effects of mechanical and thermal processing of the alloy permit higher design stresses to be incorporated than are permitted for the conventional alloy.

The chemical balance allows the nickel steel alloy to exhibit excellent resistance to carburization, oxidation and nitriding atmospheres. The principle di?erence between alloys 800H and 800HT? is the restricted aluminum and titanium content in 800HT?, which results in higher creep and stress rupture properties. Incoloy 800, 800h and 800ht materials can be used up to 800 ¡ã C. Incoloy 800, incoloy 800h, incoloy 800ht also known as alloy 800, alloy 800h, alloy 800ht. The higher strength results from close control of the carbon, aluminum, and titanium contents in conjunction with a high-temperature anneal. Incoloy 800HT will not become embrittled even after long periods of usage in the 1200-1600¡ã F range where many stainless steels become brittle.
