Applications
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.
- Chemical processing and production of pharmaceuticals, pesticides, and synthetic fibers
- Production of acetic acid, vinyl chloride monomer, and hydrogen fluoride
- Gas scrubbers, heat exchangers, and evaporators in marine environments
- Equipment for flue gas desulfurization systems
- Nickel wetted parts in chlorine dioxide bleach plants
- Digesters and bleach plants in paper and pulp industries
- Scrubbers and cooling towers in power plants.
Material Summary
HASTELLOY B-3 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. B-3 alloy has a special chemistry designed to achieve a level of thermal stability greatly superior to that of its predecessors, e.g. HASTELLOY B-2 alloy. B-3 alloy has excellent resistance to pitting corrosion, to stress-corrosion cracking and to knife-line and heat-affected zone attack.
Hastelloy B-3 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 B-3 seamless pipe is a common form of Hastelloy B-3 material, which is widely used in chemical industry, aerospace, marine engineering and other fields.
