What is Hydrogen Damage and what causes it?

  • Includes embrittlement, blistering, cracking due to
    precipitation of hydrogen in the microstructure,
    hydrogen attack, hydride formation.

  • Embrittlement, blistering and cracking occur at
    ambient temperatures.

  • Hydrogen attack is elevated temperature problem
    with carbon and alloy steels.

  • Hydrides embrittle and cause cracking in titanium,
    tantalum, zirconium, and other transition metals.
