Steel wire is one of the four types of steel plates, tubes, shapes, and wires. It is a reprocessed product made from hot-rolled wire rod and cold-drawn.
According to the shape of the section, there are mainly circle, square, rectangle, triangle, ellipse, flat, trapezoid, zigzag, etc.; according to the size, there are extra fine <0.1 mm, finer 0.1~0.5 mm, finer 0.5~1.5 mm, medium 1.5~3.0mm, 3.0~6.0mm thick, 6.0~8.0mm thick, extra thick>8.0mm; classified by strength, there are low strength <390 MPa, low strength 390~785 MPa, normal strength 785-1225 MPa, high-strength 1225~1960 MPa, high-strength 1960~3135 MPa, extra-high strength >3135 MPa; classified by purpose: ordinary quality steel wire includes welding rod, nail making, net making, packaging and printing industry Steel wire, steel wire for cold heading for cold heading rivets, screws, etc. Electrical steel includes special steel wire for the production of overhead communication lines, steel core aluminum stranded wire, etc. Steel wire for textile industry includes thick combs, healds 013, card clothing and needles Steel wire, rope-making steel wire is exclusively for the production of steel wire ropes and spokes. Spring steel wires include steel wires for springs and spring washers, piano and tires, cords and transportation tapes. Structural steel wires refer to steel wires for the watch industry, ball, automatic machine free cutting, and stainless steel wires. Including the stainless steel wires and surgical implant wires for the above-mentioned purposes, the resistance alloy wires are used for heater elements and resistance elements, and the tool wires include steel wires and shoe wires.
