Hastelloy C276 & C22 - Key Material Supplier for Hydrogen Energy Storage

Description of Hastelloy C276 & C22 Tubing

What is Hastelloy C276 & C22 Tubing?

As a premier supplier of advanced materials for the hydrogen energy sector, we provide high-performance Hastelloy C276 and Hastelloy C22 alloys. These nickel-chromium-molybdenum alloys are engineered to withstand the extreme challenges of hydrogen storage and hydrogen transport infrastructure, ensuring maximum safety, durability, and efficiency in your clean energy systems.、

Hastelloy C276 and Hastelloy C22 are versatile nickel-chromium-molybdenum alloys renowned for their exceptional corrosion resistance. In the rapidly growing hydrogen economy, these materials are critical for handling high-pressure hydrogen, preventing embrittlement, and resisting corrosion from impurities and electrolytes. They are the materials of choice for the most demanding components in hydrogen production, storage, and transportation applications.

Key Features of Hastelloy C276 & C22 Tubing

The superior performance of our Hastelloy C-series alloys in hydrogen service is due to a unique combination of properties:

• Exceptional Resistance to Hydrogen Embrittlement:

  Maintains ductility and toughness when exposed to high-pressure hydrogen gas, a critical factor for hydrogen storage vessel and pipeline safety.

• Outstanding General Corrosion Resistance: 

  Effectively resists a wide range of corrosive media, including acids, chlorides, and sour gases (H₂S).

• Superior Localized Corrosion Resistance: 

  Highly resistant to pitting, crevice corrosion, and stress corrosion cracking (SCC) in chloride-containing environments, which is vital for hydrogen transport through pipelines.

• Excellent Weldability: 

  Both Hastelloy C276 and C22 can be readily welded using common techniques, facilitating the fabrication of complex components for hydrogen energy storage systems.

• High Strength at Elevated Temperatures: 

  Retains mechanical properties at the operating temperatures encountered in electrolyzers and compression systems.
