800/800H/800HT  Characteristic as below
1.Excellent corrosion resistance in the water media of the extremely high temperature of 500°C.
2.Good stress corrosion resistance
3.Good machining Incoloy 800/800H/800HT Metallurgical structure
800H is face-centered cubic lattice structure. very low carbon centent and increased Ti:C rate
improve the stability of the structure, anti-allergy , and anti-intergranular corrosion. Low temperature annealing of 950°C ensure the fine grain structure. Incoloy 800/800H/800HT Corrosion resistance
800H 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.
800H 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 800/800H/800HT  Application range and field
1.Nitrate condenser---Corrosion resistance of nitrc acid
2.Steam heating pipes--Very good mechanical property
3.Heat up element tube--Very good mechanical property For the application of up to 500°C enviornment, alloy supply state change to annealing.
