Corrosion Resistance Of Incoloy 800H
Incoloy 800H is resistant to many corrosive media. Its high nickel content makes it resistant to stress corrosion cracking in aqueous corrosion conditions. The high chromium content provides better resistance to pitting and crevice corrosion cracking. The alloy has good corrosion resistance to nitric acid and organic acids, but limited corrosion resistance in sulfuric acid and hydrochloric acid. Good corrosion resistance in oxidizing and non-oxidizing salts, in addition to the potential for pitting corrosion in halides. It also has good corrosion resistance in water, steam and mixtures of steam, air and carbon dioxide.
Incoloy 800H Has The Following Properties
1. Excellent corrosion resistance in extremely high temperature aqueous media up to 500°C
2. Good resistance to stress corrosion
3. Good workability
Incoloy 800H Application Areas
1. Nitric acid condenser - resistant to nitric acid corrosion
2. Steam heating tube - good mechanical properties
3. Heating element tube - good mechanical properties
For applications up to 500°C, the alloy is supplied in the annealed condition.
