Abstract: In order to explore the compatibility of materials and hydrogen gas medium, the hydrogen embrittlement (HE) evaluation of the 316L and 16Mn materials were executed. The test samples were WOL specimen, and the test environments included (room temperature, 90 MPa) and (90 ℃, 90 MPa). The results showed that, there was no cracking at the loaded stress intensity factor KI of 70.36 MPa·m1/2 for 316L and 83.50 MPa·m1/2 for 16Mn. Considered the requirements of the material compatibility with hydrogen in the ISO standard, this paper proposed that we couldn’t choose to evaluate the compatibility of materials with hydrogen when the tensile strength was lower than 710 MPa for 316L and 515 MPa for 16Mn.
