Abstract: PURPOSE: A method is provided to manufacture a sintered porous stainless steel sheet with gradient pore structures having superior filtering and sound absorption effects using waste byproducts generated when manufacturing stainless steel rods. CONSTITUTION: The method for manufacturing a porous stainless steel sheet with gradient pore structures using waste stainless steel scrap fiber comprises the steps of removing polymer material contained in byproducts of the waste stainless steel scrap fiber generated during the process of producing a stainless steel rod; laying up stainless steel scrap in a stainless steel web shape having a lamellar structure; and adhering each of adjacent portions of the scraps forming the stainless steel web laid up the above step, wherein the polymer material contained in the waste stainless steel scrap fiber is removed with a toluene solution which is mixed with a dispersing agent, the stainless steel scrap is laid up so that a size of the stainless steel scrap is continuously varied in the formation step of the stainless steel web, and the adhesion of the stainless steel scraps onto the adjacent portions is performed through sintering treatment.
