Product Information

• Inconel Series

INCOLOY 800 (UNS N08800/W. Nr. 1.4876) is a widely used material for construction of equipment requiring corrosion resistance, heat resistance, strength, and stability for service up to 1500°F (816°C). Alloy 800 offers general corrosion resistance to many aqueous media and, by virtue of its content of nickel, resists stress corrosion cracking. At elevated temperatures it offers resistance to oxidation, carburization, and sulfidation along with rupture and creep strength. For applications requiring greater resistance to stress rupture and creep, especially at temperatures above 1500°F (816°C), INCOLOY alloys 800H and 800HT are used.

• Chemical Properties of Incoloy 800

Application

• Some typical applications are:

• Heat-treating equipment such as baskets, trays, and fixtures.
• Chemical and petrochemical processing,
• Heat exchangers and other piping systems in nitric acid media especially where resistance to chloride stress-corrosion cracking is required.
• Nuclear power plants, it is used for steam-generator tubing.
• Domestic appliances for sheathing of electric heating elements.
• Production of paper pulp, digester-liquor heaters are often made of alloy 800.
• Petroleum processing, the alloy is used for heat exchangers that air cool the process stream.
