Hastelloy B3 is a nickel-molybdenum alloy that is highly resistant to corrosion by reducing atmospheres, such as hydrogen chloride gas and sulfuric acid. It contains a higher concentration of chromium and molybdenum, making it more resistant to pitting and crevice corrosion in chloride-containing environments.

HASTELLOY B3 alloy (UNS N10675) is an excellent resistance alloy to hydrochloric acid at all concentrations and temperatures. It also withstands sulfuric, acetic, formic and phosphoric acids, and other nonoxidizing media. B3 alloy has a special chemistry designed to achieve a level of thermal stability greatly superior to that of its predecessors, e.g. HASTELLOY B2 alloy. B3 alloy has excellent resistance to pitting corrosion, to stress-corrosion cracking and to knife-line and heat-affected zone attack.

Hastelloy B3 is a nickel-based alloy with excellent corrosion resistance and resistance to stress corrosion cracking. Its main components include nickel, molybdenum, iron, chromium and other elements. Hastelloy B3 seamless pipe is a common form of Hastelloy B-3 material, which is widely used in chemical industry, aerospace, marine engineering and other fields.
