  800H alloy has the following characteristics:,

  Excellent corrosion resistance in extremely high temperature water-based media up to 500C.

  Excellent resistance to stress corrosion.

  Good processability.

  
  

  Metallographic structure of Incoloy 800H:

  800H is a face centered cubic lattice structure. Extremely low carbon content and increased Ti: C ratio increase structural stability and maximum resistance to sensitization.

  And resistance to intergranular corrosion. Low temperature annealing at around 950C ensures a fine-grained structure.

  
  

  Corrosion resistance of Incoloy 800H:

  800H can withstand corrosion from many corrosive media, and its high iron content makes it have good resistance to stress corrosion cracking under water-based corrosion conditions. Although Gaoming contains it, it has better resistance to spot corrosion and crevice corrosion cracking. This alloy has good resistance to nitric acid and organic acid corrosion, but its corrosion resistance is limited in sulfuric acid and hydrochloric acid. Besides the possibility of point corrosion in halides, it has good corrosion resistance in both oxidizing and non oxidizing salts. It also has good corrosion resistance in mixtures of water, steam, steam, air, and carbon dioxide.
