A new concept in implementing hydrogen embrittlement (HE) mitigation on nuclear piping materials was suggested by using electro-transport treatment. The electro-transport treatment can be applied to reduce HE susceptibility and thus make the material more resistant to hydrogen damage. To demonstrate the validation of the developed method, the effect of hydrogen on the tensile properties of SA-508 Grade 1A low alloy steel was investigated by slow strain rate test. Material characteristics were observed as a function of hydrogen charging condition and electro-transport treatment. Based on these experimental results, the electro-transport treatment was proposed as a potential method for mitigating the HE susceptibility to replace the conventional post-weld heat treatment.
