PPH2 - Material for Hydrogen Components

POPPE + POTTHOFF GmbH Hall: B7 Stand: 7A30

PPH2 is a specialized alloyed carbon steel designed for the demanding requirements of hydrogen storage and transport. Unlike austenitic stainless steel, which requires thick-walled components due to its lower strength, PPH2 offers significantly higher mechanical performance. This allows the design of thinner and lighter components without compromising pressure resistance.

A key advantage of PPH2 is its resistance to hydrogen diffusion, which is further enhanced by a proprietary PPSH heat treatment. As a result, components made from PPH2 not only reduce weight and material consumption but also lower CO₂ emissions during production.

Poppe + Potthoff uses PPH2 to manufacture high-pressure pipes and distribution rails for hydrogen systems operating at up to 700 bar. These components are EC79-certified and have passed the demanding HGV3.16 tests, confirming their suitability for modern hydrogen technologies.
