Incoloy 800H pipe is a high temperature nickel-iron-chromium alloy known for its excellent creep and rupture strength for demanding applications. It is essentially an enhanced version of Incoloy 800, with excellent performance at high temperatures due to controlled carbon content and high temperature annealing. This makes it a top choice for heat exchangers, furnace components and other equipment exposed to high temperatures and corrosive environments.
What is INCOLOY 800 Pipe?
Incoloy 800 Pipe is a nickel-iron-chromium alloy pipe that has good strength and excellent resistance to oxidation and carburization in high temperature environments. It has excellent corrosion and heat resistance, making it an ideal choice for applications such as petroleum refining, chemical processing, and power generation.
