FAQ:

Q1: Why is Hastelloy C22 considered a superior material for hydrogen storage applications?

A: Hastelloy C22 offers an exceptional balance of corrosion resistance and mechanical strength. Its primary advantage for hydrogen storage is its outstanding resistance to hydrogen embrittlement, which prevents catastrophic failure and ensures the safety and long-life of high-pressure storage tanks and systems.

Q2: How does the performance of Hastelloy C22 compare to stainless steel (e.g., 316L) in hydrogen service?

A: While stainless steels like 316L are used in some less demanding applications, Hastelloy C22 provides far superior resistance to hydrogen embrittlement, chloride-induced stress corrosion cracking, and general corrosion. This makes Hastelloy C22 the preferred high-performance alloy for critical, high-pressure, and long-duration hydrogen storage and transportation where reliability is non-negotiable.

Q3: Can Hastelloy C22 be used for both gaseous and liquid hydrogen storage?

A: Yes. Hastelloy C22 maintains excellent mechanical properties at both the elevated temperatures found in some system operations and the cryogenic temperatures required for liquid hydrogen storage. Its toughness and ductility at low temperatures make it a reliable choice.

Q4: Is Hastelloy C22 easy to weld for fabricating large hydrogen pressure vessels?

A: Yes. Hastelloy C22 is known for its excellent weldability by most standard techniques, including GTAW (TIG) and GMAW (MIG). The weldments retain good corrosion resistance, which is crucial for fabricating large, complex hydrogen storage containers.
