Description
Incoloy 800 resists sulfur attack, internal oxidation, scaling and corrosion in a multitude of environments. Alloy 800 is used in a variety of applications involving exposure to corrosive environments and high temperatures. It is used for heat-treating equipment such as baskets, trays, fixtures, and used for heat exchangers and other piping systems in nitric acid media.

Features: Incoloy 800 has good rupture and creep strength and excellent resistance to oxidation, carburization and sulfidation at temperatures up to 816℃. It also resists general corrosion by many aqueous media. For Applications requiring higher stress rupture and creep properties, especially at temperatures above 816℃, Incoloy 800H and 800HT are recommended. Incoloy 800 is readily formed, welded and machined.
Applications: Chemical and petrochemical process piping, heat exchangers, furnace components, carburizing equipment, heating-element sheathing, and nuclear power steam-generator tubing.
