Project Description

Hastelloy B (UNS N10001)

Hastelloy B (UNS N10001) is a surface centered cubic lattice. By controlling the minimum value of iron and chromium, the processing brittleness is reduced and the precipitation of Ni4Mo phase between 700-870℃ centigrade is prevented.

  • Control the iron and chromium elements at the lowest level to prevent the formation of β phase Ni4Mo.
  • Excellent corrosion resistance to the reduction environment.
  • Excellent medium concentration of sulfuric acid and many non oxidizing acid corrosiveness.
  • Good resistance to chloride ion reduction of stress corrosion cracking (SCC).
  • Excellent ability to endure a variety of organic acid corrosion.


Hastelloy B has a wide range of applications in the fields of chemical, petrochemical, energy manufacturing and pollution control, especially in sulfuric acid, hydrochloric acid, phosphoric acid, acetic acid and other industries.
