Hydrogen embrittlement, sometimes called “metal embrittlement,” is a common problem for hydrogen service, and one that can be prevented by choosing properly designed valves for low-temperature hydrogen service. In this blog, we explain what hydrogen embrittlement is and what can be done to prevent it.
Hydrogen, specifically green hydrogen, is growing in popularity as countries and industries look for climate-friendly energy solutions that reduce reliance on fossil fuels. As demand grows, so does the need for developing a safe, reliable infrastructure that makes that transition more feasible.

As hydrogen continues to increase in popularity, a particular focus is finding valves and components that are tough enough to stand up to hydrogen. By affecting the electrochemical kinetics of certain metals, hydrogen can cause pitting and acceleration of the rate of inter-granular corrosion of high-strength steels, titanium alloys and aluminum alloys, which are the most vulnerable metals. Additionally, the interaction of hydrogen and stress can result in escalated stress-corrosion cracking susceptibility of steel, particularly in welded joints.
