Before we start describing steel wire, let's understand what it is. We have all seen the wire and we know that its color can be completely different - from bright fiery to light silvery. A wire is a long metal cord or thread of various thicknesses. As for the metal from which this material is made, it can be copper, aluminum, steel, titanium, zinc, as well as their alloys. The most common wire is round, although it can be square, as well as trapezoidal, but much less often.
Types of wires
Due to excellent physical and performance characteristics, one of the most common types of this material is steel wire. It can be made in several different ways. One of them is cold drawing. The essence of this technology lies in the fact that a preheated metal billet is pulled (dragged) through a hole with a smaller diameter. Steel wire is a kind of rolled profiles that differ in shape. Depending on the purpose, it can be welding (GOST 2246-70), springy (GOST 9389-75), reinforcing (asreinforcing element in a reinforced concrete structure), etc.
Varieties of steel wire
Currently, there are three main categories of steel wire:
- Low carbon steel wire
- Doped wire
- High alloyed wire
The most popular variety is low-carbon steel, in which the carbon content is much lower than in other types of steel. For example, one of the main characteristics of this type of wire is a small sensitivity to elevated temperatures, for example during welding. In addition, we can name a high level of corrosion resistance, flexibility and toughness. Most often, steel wire from mild steel is produced with a section diameter that ranges from 0.2 to 8.0 mm. This material is made by the method of repeated cold drawing.
Assignment of different types of wire
By purpose, as mentioned above, steel wire can be classified as follows.
- Knitting wire. This type of rolled metal is most often used for linking various enclosing structures or for the production of nails. This type of wire is also called "trading". It is always made of low carbon steel, and according to the nature of the external coating, it can be galvanized and non-galvanized.
- Grade wire is generally used formanufacture of consumer goods. Always made from high carbon steel.
- Spring wire, as the name implies, is used for the manufacture of various types of springs by exclusively cold winding. No hardening process.
If we consider steel wire products, the following examples can be given: springs, nails, screws, rivets, screws, ropes, rebar, obstacles, fences.
