Abstract: Additive manufacturing (AM) of high-strength steels has become one of the main technological directions in the field of metal additive manufacturing. Firstly the research progress and frontier dynamics of AM metallic materials and technologies are traced, the relevant studies on the key grades of three types high-strength steels has been analyzed respectively, including low alloy ultrahigh-strength steels, high alloy ultrahigh-strength steels and stainless high-strength steels, the relative works on powder metallurgy, printing process, heat treatment, microstructure and mechanical properties of various typical high strength steel have been summarized in detail.Secondly it focuses on the typical applications and main achievements of AM high-strength steels at home and abroad. Furthermore, in view of current shortcomings in the development of the system establishment of AM high-strength steels, relevant suggestions are put forward in three aspects including the forward design and research of special alloys, the development of large-scale high-precision and intelligent facilities, and the system construction of standards. Based on the analysis of research and application progress of AM high-strength steels, the focus of key areas direction and the further development trend of relevent technologies are proposed, in order to further promote the industrial application of AM high-strength steel.

Key words: Additive Manufacturing (AM), High Strength Steels, Manufacturing Processes, Microstructure, Mechanical Properties
