Steel circle in Krasnodar and Crimea
Steel circle is a round section billet created in various ways and is practically the most demanded type of rolled metal. It consists of alloy, carbon and low-alloy steel. Steel circle is widely used in industry for the production of pipes and various billets. It also serves as integral elements in springs and springs, which are used during the production of cutting tools and many types of rail fasteners.
The diameter of the steel circle can be from 5 to 300 mm. Products with a diameter of less than 9 mm are produced in coils, the rest - in bars.
The length of the product can be from 2 to 12 meters. Catfish are in demand and popular with a length of 6 meters. High-alloy steel products are made 1-6 meters long.
Specifications
Steel circle has the following classification:
According to the type of accuracy, the following types are distinguished:
- normal precision;
- increased accuracy;
- high precision.
By appointment, a circle of steel is:
- general purpose - welded structures, bolted and riveted structures;
- special - double-turn washers.
The length of the product is:
- measured length;
- unmeasured length.
By the type of processing used, the product can be:
- smooth surface;
- with grooved surface.
By the type of manufacturing steel circle is divided:
- cold-drawn;
- hot rolled.
The following steels are used for the production of the circle:
- corrosion-resistant;
- heat resistant;
- quality carbon;
- carbonaceous of ordinary quality;
- doped;
- tool carbon;
- and specific brands.
Steel circle must fully comply with the current GOST.
Hot-rolled steel circle is produced with a diameter of 20 - 270 millimeters, with a length of 1 - 6 meters (high-alloy steel). Quality carbon steel and alloy steel are 2 - 6 meters long. A circle of steel made of low-alloy steel is 2 - 12 meters long, the same length is used to produce steel or carbon of the usual quality.
Calibrated rolled products can have a diameter ranging from 3 to 100 millimeters.
A circle of steel is a variation of construction and billet rolled products, made in the form of a bar with a circular cross-section. It is very often used in mechanical engineering and as a semi-finished product for pipes. If a steel circle has a diameter of up to 9 millimeters, it is produced in a motor
