Hastelloy B-2

Hastelloy B-2 has significant resistance to reducing environments like hydrogen chloride gas, and sulfuric, acetic and phosphoric acids. The presence of Molybdenum provides significant corrosion resistance to reducing environments. Alloy B-2 provides resistance to pure sulfuric acid and a number of non-oxidizing acids.
