Microstructure, Mechanical Properties, and Corrosion Behavior of 06Cr15Ni4CuMo Processed by Using Selective Laser Melting

A new class of martensitic stainless steel, namely 06Cr15Ni4CuMo, with applications in marine engineering, was processed by using selective laser melting (SLM). body-centered cubic microstructure observed, and the compared wrought 410 steel. The SLM-processed sample showed a hardness 465 ± 10 HV0.5, which nearly 115 HV0.5 less than counterpart. Similarly, improved YS UTS, sample. However, reduced ductility observed due to presence high dislocation density these samples. In addition, 71% volume high-angle grain boundaries were corroborating strength material. corrosion behavior investigated seawater, resistance found be 0.025 mmpy for 06Cr15Ni4CuMo steel 0.030 alloys, showing better
