General properties
Alloy 800H/HT / Incoloy 800H/HT ® (W-Nr. 1.4958, 1.4959; UNS N08810, N08811; DIN 17459, 17460)
Nickel-iron-chromium alloy having the same basic composition as Alloy 800 but with significantly higher creep-rupture strength. The higher strength results from close control of the carbon, aluminium, and titanium contents in conjuction with a high-temperature anneal.
Used in chemical and petrochemical processing, in power plants for super-heater and reheater tubing, in industrial furnances, and for heating equipment.
