Incoloy 800HT｜Alloy 800HT｜N08811｜Pipe and Tube

Incoloy 800HT （Alloy800HT，UNS08811） is a fully austenitic low-carbon nickel iron chromium alloy of the same series as Incoloy 800, and the cobalt content in this alloy can be strictly controlled below 0.01%.

The alloy can withstand corrosion from many corrosive media. Its high nickel content makes it have good resistance to stress corrosion cracking under water-based corrosion conditions. The high chromium content gives it better resistance to spot corrosion and crevice corrosion cracking. This alloy has good resistance to nitric acid and organic acid corrosion, but its corrosion resistance is limited in sulfuric acid and hydrochloric acid. Besides the possibility of point corrosion in halides, it has good corrosion resistance in both oxidizing and non oxidizing salts. It also has good corrosion resistance in mixtures of water, steam, steam, air, and carbon dioxide.
