Characteristic:
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 ºC.
Corrosion resistance
Ni-Mo alloy Hastelloy B-2, the carbon and silicon content is extremely low, reducing the HAZ carbon and other impurities  precipitation, so the weld has sufficient corrosion resistance. Alloy Hastelloy B-2 in the reduction of medium with very good corrosion resistance, such as a various temperature and concentration of hydrochloric acid. In the middle of the concentration of sulfuric acid solution (or contain a certain amount of chloride ions) also has very good corrosion resistance. At the same time can be used to acetic acid and phosphoric acid environment. Alloy material suitable only in the metallurgical structure and pure crystal structure in order to have the best corrosion resistance.
Applied field:
Alloy Hastelloy B-2 with a wide range of applications in the field of chemical, petrochemical, energy manufacturing and pollution control , particularly in the sulfuric acid, hydrochloric acid, phosphoric acid, acetic acid, and other industries.
