Summary:This study provides an insight into the comparison of the tensile properties between 17-4 PH SS samples processed by Selective Laser Melting (SLM) and the wrought 17-4 PH samples. The tests were conducted according to the international standard ASTM E8 and the microstructural studies were also performed. The SLM built part revealed superior tensile properties against the wrought sample. Furthermore, the SLM processed sample displayed significantly higher ductility and ultimate tensile strength (UTS) with respect to wrought samples. The microstructure of the SLM-built samples showed higher proportion of retained austenite compared to wrought samples.
