High quality incoloy alloy 800 plate nickel ASTM B409 for industry
Incoloy alloy 800 plate nickel ASTM B409 resists sulfur attack, internal oxidation, scaling and corrosion in
a multitude of environments.
Incoloy alloy 800 plate nickel ASTM B409 is used in a variety of applications involving exposure to
corrosive environments and high temperatures. It is used for
heat-treating equipment such as baskets, trays, fixtures, and used
for heat exchangers and other piping systems in nitric acid media.

About Incoloy 800H Nickel Alloy
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 are 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
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 above
1100°F (600°C). It remains ductile during long term use at
temperatures below 1290°F (700°C) due to a maximum titanium and
aluminum content of 0.7%. Alloy 800 with a standard anneal is
recommended for service below 1100°F (600°C). Alloy 800H resists
reducing, oxidizing and nitriding atmospheres, as well as,
atmospheres that alternate between reducing and oxidizing. The
alloy remains stable in long term high temperature service.
Alloy 800HT has excellent creep strength at temperatures above
1290°F (700°C). If the application involves frequent temperature
excursions under 1290°F (700°C) or parts of are permanently exposed
to a temperature below 1290°F (700°C), Alloy 800H should be
utilized. The high temperature resistance of Alloy 800HT is
comparable to Alloy 800H. It also remains stable in long term high
Alloys 800H and 800AT are easily welded and processed by standard
shop fabrication practices.
