摘要：
A mold and die metallic material, an air-permeable member for mold and die use, and a method for making the same are provided. The mold and die metallic material is made by forming a mixed material containing stainless steel fibers with an equivalent diameter of 30-300 μm and a length of 0.4-5.0 mm, and stainless steel powder, heat sintering a green body of the mixed material, and heating the sintered body thus obtained in a nitrogen atmosphere and nitrided; wherein average open pore diameter thereof is 3-50 μm.
