Incoloy 800H Corrosion resistance
800H can not be corroded in many kinds of media. Its higher nickel content made it have good stress corrosion resistance cracking properties in the water corrosion condition. High chromium content made it better resistance to pitting and crevice corrosion cracking. This alloy can resist nitric acid and organic acid, but it is not so fine in the sulfuric acid and hydrochloric acid.
800H have good corrosion resistance to both oxidation and non-oxidizing salt, but maybe a little pitting in halide, and also excellent properties in the mixture of water, smoke, steam, air and carbon dioxide.
Incoloy 800H Application range and field
1. Nitrate condenser---Corrosion resistance of Nitric acid
2. Steam heating pipes--Very good mechanical properties
3. Heat up element tube--Very good mechanical properties
