Incoloy 800/800H/800HT®
Alloys 800H (UNS N08810) and 800HT (UNS N08811) are dual certifiable Nickel-Iron-Chromium materials that resist oxidation, carburization and other high-temperature corrosion. The chemical composition of the two alloys is identical to Alloy 800 (UNS N08800), except for the higher level of carbon present in both grades —(0.05 – 0.10%) in alloy 800H and(0.06 – 0.10%) in alloy 800HT. Alloy 800HT also has an addition of up to 1.0% aluminum and titanium. The restricted chemical compositions, combined with the high temperature anneal, assure these materials have more significant creep and rupture strength than Alloy 800. Alloy 800H has good creep-rupture properties at high temperatures
