Incoloy 800HT is an all-austenitic low-carbon nickel-iron-chromium alloy of the same series as Incoloy 800. The cobalt content in the alloy can be strictly controlled below 0.01%.
Incoloy 800HT is resistant to corrosion by many corrosive media. Its high nickel content makes it have good stress corrosion cracking resistance under water-based corrosion conditions.
Incoloy 800HT has the following characteristics
Excellent corrosion resistance in extremely high temperature aqueous media up to 500ºC
Good resistance to stress corrosion
Good processability
