Abstract
The studies related to hydrogen damage of stainless steels have been reviewed with emphasis on the recently published results. This review is composed of seven items, preface, diffusion and trapping behavior of hydrogen, internal hydrogen embrittlement, hydrogen environment embrittlement, hydrogen damage at the elevated temperature, creep behavior in hydrogen environment, and anomalous corrosion by hydrogenation. Special attention is given for hydrogen damage of austenitic stainless steels.
