ASME SB 409 UNS N08810 Plate contains nickel, iron and chromium, which provide greater corrosion resistance when exposed to high temperatures. Incoloy 800H Plate also has excellent resistance to oxidation, carburization and sulfidation. Added carbon, as well as annealing, also improves the creep rupture strength of Inconel 800h Plate. It also has high machinability.
ASME SB 409 UNS N08810 Plate has good creep rupture properties at temperatures up to 1100°F (600°C). With a maximum content of 0.7% titanium and aluminum, 1.4958 material can remain ductile for long-term use at temperatures up to 1290°F (700°C).
Incoloy alloy 800H resists reducing, oxidizing, and nitriding atmospheres, as well as atmospheres that alternate between reducing and oxidizing.
