INCOLOY 800HT Seamless Pipes


The INCOLOY® 800HT series of alloys offer good strength retention under exposure to extremely corrosive and high temperature environments along with having good creep and rupture strength. They have found wide usage in chemical plants, refineries and power generation facilities.

Suitable applications are found in process piping, heat exchanger and furnace manufacture.

Incoloy 800HT is primarily used in applications with temperatures up to 1100° F, where alloys 800H and 800HT are normally used in temperatures above 1100° F where resistance to creep and rupture is required. The chemical balance allows the nickel steel alloy to exhibit excellent resistance to carburization, oxidation and nitriding atmospheres. Incoloy 800HT will not become embrittled even after long periods of usage in the 1200-1600° F range where many stainless steels become brittle. Excellent cold forming characteristics typically associated with the nickel-chromium alloys are exhibited with 800HT. When cold formed extensively the grain size produces a visibly undulated surface called [orange peel". Incoloy 800HT can be welded by the common techniques used on stainless steels.
