Corrosion resistance of Incoloy800H:
800H can resist the corrosion of various corrosive media. Its high nickel content makes it have good stress corrosion cracking resistance under water corrosion conditions. The high chromium content makes it have better resistance to pitting corrosion and crevice corrosion cracking. The alloy has good corrosion resistance to nitric acid and organic acid, but its corrosion resistance in sulfuric acid and hydrochloric acid is limited. 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 the mixture of steam, air and carbon dioxide.
Incoloy800H application scope The application fields are:
1. nitric acid condenser-nitric acid corrosion resistance
2. Steam heating pipe-good mechanical properties
3. Heating element tube-good mechanical properties
For applications up to 500℃, the supply state of the alloy is annealed.
