Incoloy 800HT (NO8811) nickel based alloy overview:

Incoloy800HT (N08811) is a full-austenitic low-carbon nickel-iron-chromium alloy of the same series as Incoloy 800. The cobalt content in this alloy can be strictly controlled below 0.01%.

Incoloy800HT (N08811) is resistant to many corrosive media. Its higher nickel content makes it resistant to stress corrosion cracking in aqueous corrosion conditions. The high chromium content makes it better resistant to pitting and crevice corrosion cracking. The alloy has good resistance to the corrosion of nitric acid and organic acids, but has limited corrosion resistance in sulfuric acid and hydrochloric acid.
In addition to the possibility of 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 mixtures of steam, air and carbon dioxide. Used in nitric acid condensers, resistant to nitric acid corrosion, steam heating, good mechanical properties, heating element tubes, good mechanical properties, etc. For applications up to 500 ° C, the alloy is supplied in the annealed state.
