Incoloy 800HT (UNS N08811 / W.Nr. 1.4959) nickel-iron-chromium alloys that have 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, power plants for super-heater and reheater tubing, industrial furnaces and heat-treating equipment.
