Incoloy Alloy 800
Alloys 800H (UNS N08810) and 800HT (UNS N08811) are dualcertifiable 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), with the exception of 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. In addition to the chemistry restrictions, both alloys receive a high-temperature annealing treatment that produces an average grain size of ASTM 5 or coarser. The restricted chemical compositions, combined with the high temperature anneal, assure these materials have greater creep and rupture strength when compared to Alloy 800. Alloy 800H has good creep-rupture properties at temperatures.
These materials are not a single material but the name for a family of corrosion resistant steels. Like many scientific breakthroughs, the origins of stainless steel lies in a lucky accident. From the smallest part of the zipper to the largest building skyscraper.
Metal fabrication is widely used across various industrial sectors such as mining, construction, manufacturing, shipbuilding, automotive, aerospace, and energy.
