Hastelloy B-2 is a corrosion-resistant, solid-solution nickel-molybdenum alloy.
Hastelloy B-2 has the following characteristics:
- Controls the iron and chromium content at low levels to prevent the formation of the β-phase Ni4Mo.
- Excellent corrosion resistance in reducing environments.
- Good resistance to moderate concentrations of sulfuric acid and many non-oxidizing acids.
- Very good resistance to chloride ion-induced stress corrosion cracking (SCC).
- Excellent resistance to corrosion by various organic acids.
