Corrosion Resistance Of Steel Wire

Jul 26, 2017

Wire Use classification has: ordinary quality steel wire including electrode, nail, net, packaging and printing wire, cold top forged steel wire for cold upsetting rivets, screws, etc., electrical steel including the production of overhead communication lines, steel core aluminum stranded wire, such as special steel Wire, steel wire for textile industry including coarse comb, needle cloth and needle wire, wire rope and spokes, Steel wire steel wire for the production of steel wires and springs, including spring and spring washers, piano, tires, cords and transport tapes, steel wire, watches industrial steel, ball, automatic machine easy to cut steel wire, Stainless steel wire includes stainless steel wire and surgical implant wire for all uses, resistance alloy wire for heater element, resistor element, tool steel wire including steel wire and shoe steel wire.

The main processes of steel wire production include raw material selection, removal of iron oxide skin, drying, coating treatment, heat treatment, wire drawing, coating treatment, etc. Steel wire Removal of oxidized skin The general process is phosphating, the removal of the oxide sheet refers to the removal of the surface of the wire rod or the intermediate strand of iron oxide skin, the purpose is to prevent the drawing of iron oxide damage mold and steel wire surface, for subsequent coating or coating preparation of good surface conditions and reduce the tension of the friction to reduce the pull force. There are two kinds of chemical and mechanical methods to remove the oxidized sheet metal, Steel wire see the chemical descaling and disk strip mechanical descaling. After the chemical descaling and coating treatment, the wire rod or the intermediate billet is dried at low temperature to remove the hydrogen and moisture. Drying temperature is generally 300 degrees Celsius, the temperature should not be too high to prevent lubrication coating failure. The hydrogen, which is the steel wire, eliminates the hydrogen in the steel base during the pickling process, in order to eliminate the hydrogen embrittlement and restore the plasticity of the rod. Steel wire Remove moisture from the surface of the wire rod so that it is dry, to prevent the use of water deterioration lubricants.

Steel wire refers to the use of multiple or more strands of fine wire twisted into a flexible rope, steel wire is made from multi-layer wire into strands, and then to the core of the rope, by a certain number of strands twisted into a spiral-like rope. In the material handling machinery, for lifting, traction, tension and bearing. Steel wire The strength of the steel wire is high, the weight is light, the work is stable, not easy to suddenly break the whole root, reliable work.


1, general purpose steel wire (including galvanized steel stranded wire): use

2, Elevator steel wire: For high-rise buildings in the elevator equipment manned in the matter, the requirements of a tight structure, soft, small structure elongation, usually 8-strand structure.

3, aviation wire: used in aircraft or air cable, the requirements of high fatigue performance and corrosion resistance.

4, petroleum steel Wire: Strong bearing capacity, corrosion resistance

5, aerial ropeway and cable car used wire: for the air transport track, Steel wire with the tramway as a means of transport, the requirements of steel wire has a greater safety factor, corrosion resistance, steel surface smooth

6, lifting steel wire: requirements of high tensile strength, soft performance, not rotating resistance to distortion fatigue, not loose.

7, Fishing wire: Used for trawl, fixed nets, rolling nets, etc., all in rivers, lakes, seawater environment, the requirements of corrosion resistance, soft performance.
