Abstract: Stainless steel porous materials were prepared by powder metallurgy method, and the effect of pore-forming material contents on the porosity and compressive strength was studied. The results show that the average porosity of the stainless steel porous materials increased and their compressive strength of the materials decreased with the increase of pore-forming material content. The mass fraction of pore-forming material being 40%-50% could make the strainless steel porous material owning high porosity.
