Stainless steel is one of the most popular types of long products. Scope and types of circles
This product is made in the form of a bar of a certain section. If the diameter is small, then the circle is wound into coils, but metal-roll of standard sizes looks like bars. It is an indispensable element in construction and repair work. This circle is directly involved in the construction of gazebos, playgrounds, various kinds of fences. It is easy to weld an aviary, a cage for animals or a lattice from it. A sieve with large cells? Again, this type of high-quality rolled metal will help out.
This circle is widely used in mechanical engineering. It is also necessary in the production of cars, ships, agricultural and other equipment. After all, it is these rods that act as blanks for parts. Stainless steel is also used for the manufacture of various containers, boilers, pipelines. In the chemical and food industries, they are directly involved in the production of installations, elements of mechanisms, etc. Even in the oil and gas industry, this circle has found its application. Do not forget about the aviation and aerospace industry. The advantages include corrosion resistance, high strength characteristics, heat resistance. But the disadvantage is a lot of weight, especially when it comes to elements of an impressive diameter. The classification of such rolled metal is done depending on the method of manufacture and accuracy. Hot-rolled products are produced with ordinary, high and increased degree of accuracy. But the calibrated rolled metal is divided into cold-rolled and cold-drawn. You can also determine the type of product by external signs. They usually undergo additional processing, as a result of which the surface acquires a darker or very light color. There are also forged circles made by stamping or pressing.
This term can also be heard in relation to the working tool of grinders. The cut-off wheel is shaped like a flat disc for high quality and fast cutting. The method of manufacture, material and processing of this product depends on the purpose. For example, a reinforced cutting wheel has increased strength. It is resistant to high temperatures. Another advantage is its durability.
Production technology - how are they born?

There are several technologies for the production of round metal products. If the hot rolling method was used for the product, then we are talking about hot-rolled circles. The billet is heated to a certain temperature and then passed through the rolls. At this time, the temperature of the workpiece is about 1000 °C. This is followed by heating by another 120 ° C, since this temperature will slightly exceed the critical one. And the last step is the cooling stage. First - water, and the process of cooling in air is completed. As a result of hardening, the material acquires the necessary properties. Steel becomes harder, its strength and wear resistance increase. In this case, the properties of the metal largely depend on the rate of heating and cooling, as well as the holding time. However, improperly selected heat treatment modes can provoke the appearance of internal stresses and, as a result, cracks. The circle corrosion-proof calibrated is made without the accompanying heating. In this case, the blanks also go to a special mill, where they are rolled. In this case, more sophisticated rolling equipment is used than for the production of hot-rolled products. The diameter of a circle produced in this way ranges from 3 to 100 mm, and if this parameter is up to 5 mm, then the finished product is wound into coils, the weight of which reaches 1.5 tons. At the request of the customer, rolled metal up to 25 mm thick can also be produced in coils. If the diameter exceeds 25 mm, then such a product is already supplied in the form of bars. Their weight depends on the thickness. The stainless steel wheel can rightly be called a universal product, since the scope of its application is extensive. In most cases, they depend on the curvature, dimensions and grade of stainless steel.
Given that the circle consists of stainless steel, which is an environmentally friendly material without harm to health, the steel circle can be used in:

     Food Industry;
     light industry;
     mechanical engineering;
     processing and chemical industries.

And taking into account the fact that the steel circle has its own classification (A, B, C), modern production technology and dimensions, it will become indispensable for the aircraft industry, the shipbuilding industry, as well as for the automotive industry. The range of application of circles made of stainless steel in the food industry is quite extensive. Due to their durable and anti-corrosion properties, the wheels have become indispensable in the preparation, handling and storage of all kinds of products. Great use of circles occurs whenproduction of components for cooking and baking foodstuffs.
In medicine, the use of stainless steel circles is also common, because they have such properties as environmental friendliness and are absolutely safe in terms of hygiene.
In the recycling process, circles are used in the manufacture of measuring instruments, in the creation of structures and equipment elements. It should be noted that circles are widely used in the construction of various objects. Such circles have a special coating on their surfaces, they can be either matte or polished.
Circles made of stainless steel can be galvanized and are used in an aggressive environment, in the manufacture of parts for electrical wires, for grounding elements. The galvanized circle, due to its coating, is perfectly protected from fires and various kinds of influences, such as the mechanical effects of the environment.
Stainless wheels have different properties, this is influenced by the chemical composition of the steel from which the metal product is made. Different steel grades have a different chemical composition, respectively, and a different content of chemicals, such as C (carbon), Mn (manganese), S (sulfur), Cr (chromium), Ni (nickel), Al (aluminum) and others. Upon agreement with the manufacturer, it is possible to order a stainless wheel with a diameter exceeding the standard maximum of 270 mm. The minimum size (5 mm) cannot be reduced. The size of all delivered products can have a measured, non-measured, multiple measured length (up to 12 meters).
It is possible to supply round stainless steel in coils (with a diameter of less than 9 mm), a larger section is supplied only in bars. When calculating the need and organizing transportation, it is recommended to take into account the data from the following tables, which show the dependence of the weight of the rolled product on its cross section.
