Steel wire

Steel wire is one of the four major varieties of steel: plate, tube, section, and wire. It is a reprocessed product made from hot-rolled wire rods and cold drawn. Classified by cross-sectional shape, there are mainly circles, squares, moments, triangles, ellipses, flattened, trapezoids, Z-shaped, etc; According to size classification, there are ultra-fine<0.1mm, relatively fine 0.1-0.5mm, fine 0.5-1.5mm, medium 1.5-3.0mm, coarse 3.0-6.0mm, relatively coarse 6.0-8.0mm, and ultra-coarse>8.0mm; According to strength classification, there are low strength<390 megapascals, lower strength 390-785 megapascals, ordinary strength 785-1225 megapascals, higher strength 1225-1960 megapascals, high strength 1960-3135 megapascals, and ultra-high strength>3135 megapascals; Classified by purpose: ordinary quality steel wire includes welding rod, nail making, mesh making, packaging and printing industry steel wire, cold forging steel wire is used for cold heading rivets, screws, etc., electrical steel includes special steel wire for producing overhead communication lines, steel core aluminum stranded wire, etc., textile industry steel wire includes coarse comb, comprehensive 013, needle cloth and needle steel wire, rope making steel wire is used for producing steel wire rope and spokes, spring steel wire includes steel wire for springs and spring washers, piano and tire, curtain cloth and transportation tape steel wire, structural steel wire refers to steel wire for watch industry, ball, automatic machine easy cutting steel wire, stainless steel wire includes stainless steel wire and surgical implant steel wire for the above purposes, resistance alloy wire is used for heating elements.
