Hastelloy Alloys
Product Details

Our Industrial-Grade Hastelloy C Series represents the pinnacle of material engineering for the demanding environments of the hydrogen energy sector. Specifically developed to address the critical challenges of hydrogen storage and hydrogen transport, this nickel-chromium-molybdenum alloy offers unparalleled safety and reliability. As the global push for clean energy intensifies, the infrastructure for hydrogen storage and hydrogen transport requires materials that can withstand high-pressure hydrogen environments while resisting the devastating effects of hydrogen embrittlement. Our Hastelloy C series is the definitive solution, providing exceptional resistance to corrosion and maintaining mechanical integrity under extreme conditions, making it the premier choice for safe and reliable hydrogen applications.

The Hastelloy C series is defined by a set of robust product characteristics that make it indispensable for hydrogen infrastructure:
Our Hastelloy C alloy is specifically formulated to resist the cracking and degradation caused by hydrogen embrittlement, a primary failure mode in hydrogen storage systems.
It exhibits outstanding resistance to a wide range of corrosive media, including chlorides, acidic environments, and other aggressive chemicals encountered during hydrogen production, transport, and storage.
The Hastelloy C material retains its mechanical properties and structural integrity at elevated temperatures, which is crucial for components in compression and storage systems.
Despite its high strength, the Hastelloy C strip and other forms can be readily welded, forged, and machined into complex components for hydrogen transport vessels and systems.
Components made from our Hastelloy C series ensure a long service life with minimal maintenance, providing a safe and reliable solution for critical hydrogen applications.
