800 Pipe, an alloy blend of nickel and chromium, encompasses the esteemed 800 series, comprising 800H and 800HT variants. Engineered to meet the demands of high-temperature environments, 800H amalgamates nickel, chromium, and iron, while its derivative, 800HT, optimizes these properties further. Recognized for their exceptional resistance to creep, these pipes offer a robust solution for applications subjected to prolonged exposure to elevated temperatures. Boasting a plethora of advantages, including high-temperature strength, resistance to oxidation and carburization, superior creep rupture strength, and corrosion resistance in both acidic and sulfur-containing atmospheres, 800HT pipes stand as a cornerstone of reliability and performance in a wide array of industrial settings.
