Abstract: PROBLEM TO BE SOLVED: To provide a metal fiber filter with pleats using metal fiber nonwoven fabric suppressing cracks on the filter medium surface due to pleat formation, having superior filtering characteristics. SOLUTION: This metal fiber filter has molded pleats in the metallic porous filter medium, and is formed in a cylindrical body with the pleats axially set. The porous filter medium has at least two or more sintered media sheet-likely formed by molding and sintering a single layer or composite layer of the metal fiber nonwoven fabric in sheet-like state, and laminated structure formed by separably superposing the media with gaps therebetween. The sintered medium is the metal fiber filter with pleats for molten polymer wherein an integrated value A of the fiber diameter d (μm), basis weight w (g/m 2 ) of the metal fiber layer composing the media, and an average density τ of the media are adjusted to satisfy the relation of following equation (1): A=Σ(di×wi)×τ=800-2,000 (1)(In equation, i is respective values in an optional metal fiber layer).

Abstract: PROBLEM TO BE SOLVED: To provide a high corrosion resistance and high strength fine wire having high tensile strength.
SOLUTION: By cold wire drawing in a third wire drawing stage 26 and aging in the subsequent aging stage 28, a high corrosion-resistance fine wire 10 having tensile strength sufficiently higher than that of a base material can be obtained. Also, since the alloy composition in the base material is essentially consisting of Ni, suitable magnetic properties, i.e., a low magnetic permeability of about 1,003 can be obtained. Further, the magnetic permeability is not increased by cold or warm plastic working differently from the case of austenitic stainless steel represented by SUS 304. Also, the Ni based alloy composition in the base material comprises 30 to 45 (weight)% Cr, high corrosion resistance can be obtained. Further, the Ni based alloy composition in the base material does not comprise expensive metals, an inexpensive corrosion resistance and high strength fine wire can be obtained.
