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