cheap barbed wire

The tensile strength of cold drawn spring steel wire is slightly higher than that of oil tempered steel wire. The large specification of cold drawn steel wire elastic force is too large, winding the spring is very difficult, so the cold drawn spring steel wire application specification is generally less than 8.0mm, oil quenching tempered steel wire application specification is generally less than 13.0mm. In fact, the diameter of 13.0mm spring is used to light tension spring steel wire, cold drawing wound made into shape and then quenched and tempered. Steel wire with diameter above 15.0mm is mostly made by heating winding process.

The iron is clean and clean, and then solvent treatment, after drying immersed in zinc liquid, iron and molten zinc reaction to produce an alloyed zinc layer, the process is: degreasing – washing – pickling – assisted plating – drying – hot dip galvanizing – separation – cooling passivation. The thickness of the alloy layer of hot plating wire mainly depends on the chemical composition of the steel silicon content, the size of the steel cross-sectional area, the roughness of the steel surface, the temperature of the zinc pot, the time of dipping zinc, cooling speed, cold rolling deformation, etc.

First, the commonly used stainless steel plate is divided into two types of 201 and 304, the actual composition of the Nestor cage is different, 304 stainless steel Nestor cage quality is better, but the price is expensive, 201 is worse. Anping 304 for imported stainless steel plate, Anping 201 for domestic stainless steel plate.

Galvanized (electroplating or hot plating) after welding mesh forming; The product is made of high quality galvanized iron wire by precise automatic mechanical welding. It has the characteristics of solid welding spot, reasonable structure, uniform mesh, smooth mesh, solid structure, strong integrity, and strong corrosion resistance. It can also be used for special mesh of floor heating in construction industry.

After annealing, iron wire will become softer and more flexible. Iron is a more active metal, and more active than hydrogen, so it is a good reducing agent. At room temperature, iron is not easy to react with oxygen, sulfur, chlorine and other non-metallic elements in dry air, its production cost is low, the use and scale is relatively wide, better protective function, so it is an important material for steel parts used in strict working environment.
