Product Description
Our Hastelloy C-series alloys are nickel-chromium-molybdenum-based superalloys specifically designed to handle the most aggressive environments. In hydrogen service, these alloys offer outstanding protection against hydrogen embrittlement—a common failure mode where metals become brittle and crack upon exposure to hydrogen. Hastelloy C276, Hastelloy C22, and Hastelloy C2000 provide a robust material solution for components in hydrogen production, hydrogen storage tanks, hydrogen compressors, and hydrogen transportation pipelines. Their superior corrosion resistance and high strength make them the reliable metal of choice for ensuring the safety and efficiency of the hydrogen energy value chain.
The Hastelloy C-series stands out due to its unique combination of properties, essential for demanding hydrogen applications:
Withstands high-pressure hydrogen environments without loss of ductility or fracture toughness, a critical feature for hydrogen storage safety.
Offers excellent resistance to a wide range of corrosive media, including chlorides, wet chlorine, and acidic conditions encountered in hydrogen production and purification.
The Hastelloy C276 alloy is a proven industry standard; Hastelloy C22 offers enhanced corrosion resistance in oxidizing media; and Hastelloy C2000 provides the widest corrosion resistance range.
Maintains mechanical properties and surface stability at elevated temperatures, which is vital for hydrogen compression and other high-temperature processes.
Can be readily welded and fabricated into complex components like hydrogen compressor parts, valves, and vessel linings.

Hastelloy C276, C22, and C2000 alloys are reliable metals because they possess an exceptional combination of high strength, ductility, and most importantly, a strong inherent resistance to hydrogen embrittlement. This prevents cracking and failure in high-pressure hydrogen storage and transportation systems, ensuring long-term operational safety.
While all three offer excellent hydrogen resistance, their optimal use depends on the specific corrosive environment. Hastelloy C276 is a versatile, widely-used alloy. Hastelloy C22 provides better resistance to oxidizing conditions, while Hastelloy C2000, with its added copper, offers the broadest resistance across both oxidizing and reducing environments, which can be critical in complex hydrogen production processes.
Yes, Hastelloy C276 alloy is known for its excellent weldability using common techniques like GTAW (TIG) and GMAW (MIG). Proper welding procedures must be followed to preserve its corrosion resistance and integrity in the weld zone for critical hydrogen infrastructure.
