Lifetime Concepts for Hydrogen Applications

Services:

  • Assessment of damage mechanisms in components; Development of corrective measures
  • Providing evidence of hydrogen brittleness
  • Selection, qualification and characterization of materials for hydrogen applications
  • Residual stress optimization to avoid cold crack formation of welding joins
  • Assistance in avoiding hydrogen brittleness in additive manufacturing processes
