Abstract： Hydrogen energy， as a new energy source， is receiving widespread attention from the international community. However， austenitic stainless steels used for hydrogen energy production， transportation， and storage inevitably suffer from hydrogen embrittlement. Hydrogen embrittlement is hardly avoided in the austenitic stainless steels prepared by traditional manufacturing processes， while additive manufacturing technology demonstrates significant advantages in manufacturing austenitic stainless steel anti-hydrogen embrittlement structural components， providing new ideas for solving the problem of austenitic stainless steel hydrogen embritlement. The research progress on the anti-hydrogen embrittlement mechanism of additively-manufactured austenitic stainless steels was overviewed， and discussions were carried out according to the following aspects： Hydrogen atom capture and hydrogen embritlement mechanisms of traditional austenitic stainless steel; Microstructure characteristics of austenitic stainless steel produced by additive manufacturing and their influence on hydrogen atom capture; The hydrogen embritlement resistance and mechanism of additive manufacturing austenitic stainless steel. This paper summarized the applications and prospects of austenitic stainless steels manufactured by additive manufacturing in hydrogen environments.
