Brief introduction to steel wire

Steel wire is one of the four major varieties of steel plate, tube, shape and wire. It is a reprocessed product made of hot-rolled wire rod by cold drawing. According to the shape of the section, there are mainly circle, square, rectangle, triangle, ellipse, flat, trapezoid, Z-shaped, etc.; classified by strength, there are low strength <390MPa, lower strength 390~785MPa, normal strength 785~1225 MPa, higher strength 1225~1960 MPa, high strength 1960~3135 MPa, extra high strength > 3135 MPa; classified by use: ordinary quality steel wire including welding rod, nail making, net making, packaging and printing industry steel wire, electrical steel including special steel wire for overhead communication line, steel core aluminum stranded wire, etc., steel wire for textile industry including carding, harness 013, card clothing and needle steel wire, rope making wire specially used for the production of steel wire rope and spokes, spring wire including spring and spring washer, piano and tire, cord and transport tape steel wire, structural steel wire refers to the watch industry, ball, automatic machine free cutting steel wire. Stainless steel wire includes stainless steel wire mentioned above and surgical implant steel wire for the above-mentioned purposes, resistance alloy wire for heater element and resistance element, tool steel wire includes steel steel wire and shoe-making steel wire.
