Stainless steel accompanies green hydrogen

The components used for the transport or storage of green hydrogen require hydrogen-resistant properties to ensure the safety of this critical infrastructure. Hydrogen atoms can diffuse into metallic materials and lead to material failure through hydrogen embrittlement. By default, stainless steels of grades 1.4435, 1.4404, and 1.4307 are used for components that come into contact with hydrogen. For particularly critical applications with extreme requirements for corrosion resistance, such as in aggressive chemical environments, stainless steels like 1.4439, 1.4462 (Duplex), and 1.4410 (Superduplex) have proven themselves due to their higher strength and improved resistance. By carefully selecting the appropriate material, it can be ensured that the integrity and safety of components in hydrogen-carrying systems are maintained over long periods.

As early as 2004, we at Sommer & Strassburger GmbH built buffer tanks for hydrogen and are pleased to support you with our many years of expertise.
