Product Description
Our Hastelloy C series is a group of nickel-based superalloys specifically formulated for the most demanding environments in hydrogen energy applications. These alloys are designed to withstand the unique challenges posed by fuel cell system operation, including high-pressure hydrogen embrittlement, corrosion from humid environments, and exposure to potentially corrosive electrolytes. By utilizing Hastelloy C series materials, manufacturers of hydrogen storage and hydrogen transportation equipment can ensure maximum safety, longevity, and reliability of their systems, contributing directly to the efficiency and viability of green hydrogen energy solutions.
The Hastelloy C series offers a superior combination of properties essential for fuel cell and hydrogen applications:
Outstanding resistance to a wide range of corrosive media, including chlorides, wet chlorine, and acidic environments, which can be present in fuel cell systems.
Maintains excellent mechanical properties and ductility even when exposed to high-pressure hydrogen, a critical factor for hydrogen storage and hydrogen transportation safety.
Provides robust mechanical strength at both ambient and elevated temperatures, ensuring structural integrity for high-pressure components.
Can be readily welded, formed, and machined into complex shapes required for sophisticated fuel cell components.
Offers proven performance and a long service life, reducing maintenance costs and downtime in critical hydrogen energy infrastructure.

The Hastelloy C series alloys, particularly C-276 and C-22, exhibit exceptional resistance to hydrogen embrittlement. Their stable austenitic microstructure prevents the degradation of mechanical properties that can lead to catastrophic failure in high-pressure hydrogen storage systems, ensuring long-term safety and integrity.
While all C series alloys are candidates, Hastelloy C-276 is often preferred for fuel cell components like bipolar plates due to its excellent balance of corrosion resistance from the fuel cell's acidic environment, good electrical conductivity, and proven fabricability into thin, complex shapes.
Both are excellent. Hastelloy C-22 offers enhanced resistance to oxidizing chlorides and pitting/crevice corrosion, which can be beneficial if the hydrogen stream contains contaminants. Hastelloy C-276 remains a cost-effective and highly reliable standard for clean hydrogen transportation systems. The choice depends on the specific service environment.
Yes. A key advantage of the Hastelloy C series is its excellent weldability. They can be readily welded using matching filler metals without significant loss of corrosion resistance in the heat-affected zone, making them ideal for fabricating complex hydrogen transportation and storage infrastructure.
