Hastelloy® B is a nickel-molybdenum alloy powder engineered for unmatched performance in highly reducing and acidic environments. Known for its exceptional corrosion resistance, Hastelloy® B powder is used in for applications exposed to aggressive chemicals.
It’s especially suited for use in sintered metal filters and in industries where durability under extreme conditions is essential.
Key Benefits of Hastelloy® B Powder
The high molybdenum content in Hastelloy® B provides excellent resistance to hydrochloric, sulfuric, and acetic acids, as well as hydrogen chloride gas, across a range of temperatures and concentrations.
Compared to previous B-type alloys, Hastelloy® B powder offers improved structural stability, an advantage during welding and fabrication processes. It is also highly ductile, allowing for easy forming and welding.
Hastelloy® B Powder Applications
Hastelloy® B powder is widely used in industries requiring high corrosion resistance and strength under harsh chemical environments, such as:
