The sintered and carburized porous stainless steel part has a porous body with a relative density between 30% and 89%, which is sintered from a stainless steel powder, wherein exposed pore surfaces inside the porous body are carburized without forming carbides and without using an activation process in advance. A carburized layer is formed and spread into the core of the sintered porous body. Thereby, the strength, surface hardness, and core hardness of the sintered body are significantly increased.
