Good mechanical properties are essential for steel parts additively manufactured (AM), especially, for load bearing components. For example, a proper impact toughness is necessary for structural steels used in marine and offshore (M & O) industry to prevent low temperature brittleness of the steels while a high fatigue strength warrant a long service span of the steels. Although the works on charpy and fatigue characteristics of AM parts are lacking, some related studies on their fracture behavior have been reported, which cover a range of steels including 316L stainless steel, maraging steel, 17-4 PH stainless steel, H13 tool steel, etc. This paper critically summaries the reported works and discusses a future direction for the study of the impact and fatigue characteristics of AM steels.
