Characteristics of  Incoloy 800HT

Excellent corrosion resistance in extremely high temperature aqueous media up to 500 ℃.

Excellent resistance to stress corrosion.

Very good processability.

Short Destription:

Incoloy 800HT can withstand corrosion from many corrosive media. Its high nickel content gives it excellent 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.
