Hydrogen embrittlement behavior of three austenitic stainless steels with 0.1–0.3 wt% N was investigated by electro-chemical charging of hydrogen. The degradation of tensile properties was alleviated by nitro- gen. Hydrogen permeation testing revealed that the increase of nitrogen content decreased the hydrogen diffusivity, and thereby, reduced the depth of hydrogen-affected zones. Intergranular cracks were formed in an early stage of deformation by hydrogen charging and reduced the strain-hardening rate. The cracks propagated further into the grains along martensite/austenite interfaces especially in steels with less ni- trogen.
