Assessing Hydrogen Compatibility of Cast Iron in Gas Grids: A Comprehensive Review

Short summary

Cast irons, the most common non-steel material in low-pressure European gas grids (under 16 bar), show minimal mechanical performance degradation when exposed to high-pressure gaseous hydrogen at ambient temperature, but can embrittle when exposed to high-temperature hydrogen or via electrochemical charging, with susceptibility linked to graphite microstructure.
