Disc rupture tests were performed on different ferrous and non-ferrous alloys in helium and hydrogen atmosphere. The ratio of the rupture pressures in both gases gives an idea of the HE and allows to select HE resistant materials for gaseous applications.The stable austenitic 316 SS does not show any HE with the disc rupture test. The metastable 304 SS embrittles after gaseous hydrogen exposure combined with deformation because strain induced martensite forms. The HE of the ferritic 430 grade is dependent on the strain rate. The tested copper, aluminium and titanium alloys did not show any HE during disc rupture testing. The Inconel 718 does show strain rate dependent HE. The obtained results are in agreement with literature. The disc rupture test results were in agreement with results obtained after cathodic charging.
