Mechanical properties and microstructures of 17-4 ph stainless steel parts produced using different binder contents (powder loading) of powder injection molding (PIM) feedstock have been studied. The tensile and wear properties have been evaluated. Wear tests were conducted by a pin-on-disk tribometer, without lubricant, at different loads and sliding distance. SEM examination of the fracture surfaces revealed good particle bonding and a high ductile fracture surface for high powder loading. The surface fractures of the bars with higher powder loading show a closed porosity. High performance properties such as fully dense, ultimate tensile strength, hardness and wear resistance are obtained with high powder loading.
