Hot rolled steel circle

Hot-rolled steel circle Description Hot-rolled steel circle, which is made in the form of a round metal bar, is a very common and popular product of long products. Depending on the purpose of the product in which it is used, it can be made from various grades of steel - structural, low-alloy, high-alloy, carbon. It can be used as a final product during the installation of metal structures, as well as a blank for other steel parts (steel circle 45). Manufacturing technology Hot-rolled circle can be used in various fields of industry and production due to its properties: smooth surface, dense and durable structure, ability to restore shape with a small bending force, a wide range of diameters, the most round section. Hot-rolled circle is produced according to which sets the standard for compliance with certain characteristics: product diameters vary from 5 to 280 mm, with a diameter of up to 9 mm it is possible to sell in coils, with a diameter of more than 9 mm - delivery in the form of a rod, length from 2 to 12 meters for products from ordinary or low alloy steel, length from 2 to 6 meters for alloy steel products, length from 1 to 6 meters for high alloy steel products. Depending on the purpose, a hot-rolled steel circle can be subjected to heat treatment. Cold-rolled steel circle has a diameter of 3 to 100 mm, it is produced by cold drawing. As a result of this treatment, the mechanical, physical and plastic characteristics of the steel are improved. According to the accuracy of execution, a hot-rolled circle of the following classes is distinguished: A (high), B (increased) and C (normal).
