Two commercial sealing alloys (Kovar® and Ceramvar® were tested in high pressure hydrogen, or after exposure to hydrogen gas for up to 17,500 h. All hydrogen pressures were 69 MPa. In no case was any ductility loss observed. It was therefore concluded that these alloys are probably safe for use in gas handling systems which contain hydrogen.
