Alloy 800AT,800H, 800HT NIckel-Iron-Chromium Alloy

Description

Alloy 800 (UNS N08800), Alloy 800H (UNS N08810) and Alloy 800AT (UNS N08811) are nickel-iron-chromium alloys designed to resist oxidation and carburization at elevated temperatures through 1 900 °F. The nickel content, 32 %, makes the alloys highly resistant both to chloride stress corrosion, cracking and to embrittlement from precipitation of sigma phase.

Also known as: Harper 800, 11L, Inconel 718, INCONEL® is a registered trademark of the INCO family of companies.
