INCOLOY® Alloy 800 H / HT

1.4876 / 1.4958 / 1.4959

UNS N08810 / UNS N08811

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 con-junction 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.
