1. Control of iron and chromium content to a minimum to prevent the generation of β-phase Ni4Mo.
2. Excellent corrosion resistance of restore environment.
3. An excellent resist to concentration sulfuric acid medium and large number of non-oxidizing acid corrosion.
4. A very good resistance of chloride reduction of stress corrosion cracking (SCC).
5. Good corrosion resistance of various organic acids.


Metallurgical structure:

Hastelloy B-2 is the face-centered cubic lattice structure. By controlling the content of iron and chromium at the minimum to reduce the processing brittle, prevent Ni4Mo precipitation during 700-870 °
