Incoloy 800 Wires/Wire Rod / Strip / Wire (UNS N08800, 1.4876, Alloy 800)
Incoloy 800 is a nickel-iron-chromium alloy with good strength and excellent resistance to oxidation and carburization in high-temperature atmospheres.
A high chromium content gives Incoloy 800 good resistance to oxidation. It also resists many aqueous media and is relatively free from stress-corrosion cracking. Incoloy 800 has excellent resistance to nitric acid at concentrations up to approximately 70% and at temperatures up to the boiling point. It also has good resistance to organic acids, such as formic, acetic, and propionic. It resists a variety of oxidizing and nonoxidizing salts, but not halide salts.
Typical applications are heat treating equipment, petrochemical pyrolysis tubing and piping systems, sheathing for electrical heating elements, food processing equipment.
