Incoloy800H UNS N08811 has the following characteristics
- Excellent corrosion resistance in extremely high temperature aqueous media up to 500 ° C
- Very good resistance to stress corrosion
- Very good processability
Metallographic structure of Incoloy 800H
800H is a face-centered cubic lattice structure. The extremely low carbon content and increased Ti:C ratio increase structural stability and maximum sensitization resistance as well as intergranular corrosion resistance. Low temperature annealing at around 950 °C ensures a fine grain structure.
Corrosion resistance of Incoloy 800H
800H is resistant to many corrosive media. Its high nickel content gives it excellent resistance to stress corrosion cracking in aqueous corrosion conditions. The high chromium content gives it better resistance to pitting and crevice corrosion cracking. The alloy has good resistance to nitric acid and organic acid corrosion, but has limited corrosion resistance in sulfuric acid and hydrochloric acid. In addition to pitting corrosion in halides, it has good corrosion resistance in oxidizing and non-oxidizing salts. It also has good corrosion resistance in water, steam and a mixture of steam, air and carbon dioxide.
