316L and 430L stainless steel fiber could be made by new metallic fiber making technology which named powder extrusion method. Diameter of those metal fiber is 5-15 ㎛ and the diameter could be controlled easily by a variation of powder size and extrusion ratio. 430L fiber web could be formed using renovated carding machine. The intersections between the fiber in 430L fiber web were bonded by sintering. The proper sintering condition was 1200℃, 60minute in vacuum. The pore size in bonded 430L web was around 10 ㎛ so this bonded web could be adopted for automobile filter.
