Specification Sheet: Alloy 800H/800HT (UNS N08810, UNS N08811) W. Nr. 1.4958, 1.4959. Nickel-Iron-Chromium Alloys Designed to Resist Oxidation and . Carburization with Higher Creep and Stress Rupture Properties than Alloy 800 (UNS N08800) Alloys 800H (UNS N08810) and 800HT (UNS N08811) are dual-certifiable Nickel-Iron-Chromium Another member of the 800 alloy family is Incoloy® 800HT. Also sold as Nickel Alloy 800HT, this nickel-iron-chromium alloy, has many of the same characteristics of other members of the 800 alloy grouping. Incoloy 800HT has roughly the same chemical composition as Incoloy 800H, differing only slightly in carbon, aluminum, and titanium levels.

Incoloy 8Incoloy 800 H is an iron-nickel-chromium alloy having the same basic composition as Incoloy 800, with significantly higher creep rupture strength. The higher strength results from close control of carbon, aluminum and titanium contents in conjunction with a high temp anneal. Datasheet. Print / Download PDF. 1.4876. ALLOY 800. Brand name.
