Incoloy is a nickel ferrochrome alloy designed for oxidation and carbonation at elevated temperatures.Incoloy alloy has many kinds: common such as Incoloy800, Incoloy800H, Incoloy800HT, Incoloy825, Incoloy840, Incoloy901, Incoloy925, Incoloy20, Incoloy330, Incoloy 25-6mo, etc.The alloy contains a small amount of the metallic elements molybdenum and copper.In reductive acid and oxidizing acid, it has good corrosion resistance, as well as good resistance to stress corrosion cracking, pitting and crevice corrosion.It has excellent corrosion resistance to sulfuric acid and phosphoric acid.The alloy has good cold and hot working properties and is easy to be formed and welded.The main products of this alloy are rods, tubes, plates, strips, wires and forgings, etc. It is mainly used in the chemical, petrochemical, nuclear and rare metal refining industries.
N08811 is a full austenitic low carbon nickel-iron-chromium alloy in the same series as Incoloy 800. The cobalt content of this alloy can be strictly controlled below 0.01%. N08811 is resistant to many corrosive media. Its high nickel content gives it excellent resistance to stress corrosion cracking in aqueous corrosion conditions. The high chromium content gives it better resistance to pitting and crevice corrosion cracking. The alloy has good resistance to nitric acid and organic acid corrosion, but has limited corrosion resistance in sulfuric acid and hydrochloric acid. In addition to 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 a mixture of steam, air and carbon dioxide. Used in nitric acid condensers - resistant to nitric acid corrosion, steam heating tubes - good mechanical properties, heating element tubes - good mechanical properties. For applications up to 500 ° C, the alloy supply is annealed.
The N08811 has the following features:
Excellent corrosion resistance in extremely high temperature aqueous media up to 500 ° C
Good resistance to stress corrosion

800HT alloy has the following characteristics:
1. Excellent corrosion resistance in extremely high temperature aqueous media up to 500 ° C
2. Very good resistance to stress corrosion
3. Very good processability
Metallographic structure of Incoloy 800HT:
800HT is a face-centered cubic lattice structure. The extremely low carbon content and increased Ti:C ratio increase structural stability and maximum sensitization resistance as well as intergranular corrosion resistance. Low temperature annealing at around 950 °C ensures a fine grain structure.
Corrosion resistance of Incoloy 800HT:
800HT is resistant to many corrosive media. Its high nickel content gives it excellent resistance to stress corrosion cracking in aqueous corrosion conditions. The high chromium content gives it better resistance to pitting and crevice corrosion cracking. The alloy has good resistance to nitric acid and organic acid corrosion, but has limited corrosion resistance in sulfuric acid and hydrochloric acid. In addition to 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 a mixture of steam, air and carbon dioxide.
Incoloy 800HT application range applications are:
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 supply is annealed.
