Round hot-rolled steel or just a circle is produced in coils and rods. The range of steel wheels and the requirements for geometry are established by GOST 2590-2006 (replacing GOST 2590-88). Technical conditions must comply with GOST 535-2005 (formerly GOST 535-88), for wheels made of ordinary carbon steel grades. Most often, ordinary carbon wheels are used from steel grade 3.

The values ​​of the weight of a linear meter and the number of meters per ton are given for reference and calculated based on the nominal dimensions of the rental products indicated in the table. The steel density is taken to be 7.85 g/cm3. The actual mass values ​​of one meter of circle may differ from the nominal ones by 1-9% depending on the diameter and accuracy of the rolled product.
When placing an order, it is necessary to take into account the deviations in the geometric dimensions and weight of the meter provided for by GOST 2590-2006.

Our company has the ability to supply steel circles of the following grades - 10, 20, 35, 45, 09G2S, 20Kh, 40Kh, 65G, 18KhGT, 30KhGSA, as well as other steel grades from stock and on order.

Specifications and useful information

Round steel is divided according to rolling accuracy:

Particularly high - AO1
High - A1, A2, A3
Increased - B1
Regular - B1, B2, B3, B4, B5

Steel circles are produced in coils (nmd), measured length (md) or unmeasured length (nd).

Round bars are produced in the following lengths:

from 2 to 12 meters - from carbon steel of ordinary quality and low-alloy steel
from 2 to 6 meters - made of high-quality carbon steel, alloy and high-alloy steel

The ovality of rolled products should not exceed 75% of the sum of the maximum deviations in diameter. In some cases, at the request of the consumer (according to the agreed specification), the ovality of rolled products may not exceed 50% of the sum of the maximum deviations in diameter.

The areas of application of round steel are very wide. Thus, circles can be used both for the manufacture of hinges in reinforced concrete products, instead of A1 reinforcement, provided they meet the strength characteristics, and in the manufacture of various metal structures, such as metal stairs and gratings. In addition, small circles are often used instead of wire rods for tying and packing heavy loads.

Wheels made from structural grades are mainly used for machining on lathes and milling machines, for the manufacture of various machine parts and mechanisms.

Steel circles are usually made in the following sizes: 6, 8, 10, 12, 14 16, 18, 20, 22, 25, 28, 32, 36. Intermediate sizes can be manufactured according to consumer requirements, for example 23, 26, 30, 34, etc. .d...

It is possible to manufacture and supply circles of large sizes, in increments of 1-2 millimeters. All Circles can be made from structural grades.
