Common Trade Names: Incoloy 800H/800HT/800AT, Alloy 800H/800HT/800AT, Ferrochronin 800H/800HT/800AT, Nickelvac 800H/800HT/800AT, Nicrofer 3220.

INCOLOY alloy 800H/800HT/800AT is designated as UNS N08810, UNS N08811 and Werkstoff Number 1.4876, 1.4958, 1.4959. It is listed in NACE MR0175 for oil and gas service. 

Nickel-iron-chromium alloys having the same basic composition as INCOLOY® alloy 800 but with significantly higher creep-rupture strength. The higher strength results from close control of the carbon, aluminum, and titanium contents in conjunction with a high-temperature anneal. Used in chemical and petrochemical processing, in power plants for super-heater and reheater tubing, in industrial furnaces, and for heattreating equipment.

Available Product Forms: 
Pipe, tube, sheet, strip, plate, round bar, flat bar, forging stock, hexagon and wire.
