A large number of types of varietal rolling can be found in the building materials market, however, a steel hot -rolled circle has been most widely used, which is widely used in the construction sector, automobile industry, as well as cosmic. Often a steel circle is called a rod that can be called universal material widely used in different sectors. For example, a circle of 40x is often used in details, where increased strength is important, in the production of carburetor springs and needles. Metal rods are used in the production of automobile parts and components, during the construction of fences, to increase the bearing capacity of materials, as a reinforcement, etc.
Different varieties of metal are used in the production of steel rods. The choice of one or another variety will depend on the conditions of use of the metal rolling. The accuracy of the circle of circle also depends on the scope. There are three categories of accuracy of the rental of a steel circle, namely:
– Category A is high accuracy of the rental;
– Category B – increased accuracy;
– Category B – ordinary accuracy.
The circle of steel can be safely called universal metal rolling, which are used in almost all areas of production. In the production of steel circles, much attention is paid to its accuracy, the compliance of the technology with the relevant standards and GOSTs. In the manufacture of the circle, it should be used precisely the material that will correspond to the future field of use of the metal rolling.
The steel of the brand ST3 is the most common material that is used in the production of steel rods, which is required to comply with GOST 2590-88, as well as a number of other technological norms. Depending on the scope of use, the steel circle can be made with different non -upper, multiple or measured lengths. If we talk about the weight of the rods, then it is calculated in grams. It is by weight that steel rods are sold by plants and factories.
