Hastelloy B2 is a nickel-molybdenum alloy designed to offer excellent resistance to reducing environments such as hydrogen chloride, sulfuric acid, acetic acid, and phosphoric acid. It has superior resistance against hydrochloric acid at all concentrations and temperatures, making it highly reliable in chemical processing industries. The alloy also prevents stress corrosion cracking and pitting, ensuring long service life in aggressive environments. Hastelloy B2 is widely used in manufacturing heat exchangers, pressure vessels, reactors, pipelines, and evaporators. Its high strength, durability, and fabrication properties make it one of the most preferred materials for handling strong chemical media.
