| Incoloy 800H®, Ferrochronin® 800, Nickelvac® 800, Nicrofer® 3220 |
Incoloy 800® is a nickel-chromium alloy with good strength and excellent resistance to oxidation and carburization. The alloy maintains stable structure during exposure to high temperature, therefore incoloy 800® has good corrosion resistance to many acidic environments. |
Available forms are seamless pipe, welded pipe, seamless tube, welded tube, bar, wire, sheet, plate, forgings, pipe fittings and flanges. |

Incoloy 800H and 800 HT are nickel-iron-chromium alloys. The alloys’ higher creep-rupture strength is the result of aluminum, carbon, and titanium contents. Incoloy 800 H and 800 HT is used in chemical and petrochemical processing, in power plants, industrial furnaces, and for heat treating equipment. |
