Description alloy Hastelloy B/B2, 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/B2 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 Hastelloy B/B2 can be used to acetic acid and phosphoric acid environment.
