The effect of manufacturing parameters on mechanical and corrosion resistance is investigated using tensile tests and electrochemical experiments for selective laser‐melted 15‐5PH stainless steel. The results demonstrate that when laser power is decreased to 150 W and scanning speed increased to 1400 mm s −1 , manufacturing defects increase. Plasticity and corrosion resistance reduce significantly. Cracks mainly originate from manufacturing defects and extend along the interface between molten pools. Corrosion occurs near manufacturing defects. Finally, the most suitable laser energy density is 130 J mm −3 for 15‐5PH stainless steel.
