Steel hexagon calibrated 22 st. 20 - this is a hot-rolled metal product in the form of rods with a hexagonal cross section.
Steel hexagons are distinguished by purpose, depending on the steel grade or on the mass fraction of chromium, nickel and copper; according to the method of further processing: hexagons made by pressure, cold drawing or cold machining; according to the manufacturing method: hot-rolled hexagons and calibrated hexagons.
Hot-rolled steel hexagon is produced in accordance with GOST 2879-88 by hot rolling on section mills. The basis for the production of a steel hexagon is a cast billet of square section.
The size of a hot-rolled hexagon is determined by the diameter of the circle inscribed in it and lies within 8–100 mm inclusive.
In terms of rolling accuracy, hot-rolled hexagon is produced in two types - increased (B) and ordinary (C) accuracy.
Calibration is also used, which allows to produce a hexagon calibrated with high dimensional accuracy.
In the production of a hexagon, a calibrated steel billet is pressed between hexagonal rolling rolls. The calibrated steel hexagon has a cross section from 3 to 100 mm in size and is produced in accordance with GOST 8560-78.
Hexagons are widely used in the manufacture of fasteners (pillars, bolts, nuts and studs), various parts and mechanisms of machines widely used in the automotive industry, components for furniture and other industries, as well as in metalworking and construction (for the frame of structures, as a carrier elements of fences, railings, stairs, etc.). The hexagon is widely used in construction and industrial production.
The advantages of a steel hexagon, as a type of rolled metal, are:
This profile is sufficiently resistant to high temperatures;
In the manufacture of the profile, a steel grade is used, which gives resistance to mechanical damage;
The profile is not susceptible to acids, to the effects of organic and inorganic substances, and is also moisture resistant;
Easy weldability;
Affordable price;
Long service life.
Application of steel hexagon
Wide application of steel hexagon
The areas of application of the hexagon are quite different depending on the method of production of this type of rolled metal.
A calibrated hexagon is needed for the production of high-precision parts and mechanisms, often in such a field as aircraft building, mechanical engineering, etc. A hot-rolled hexagon is very convenient as a blank for hot forging by rolling on forging rolls, as well as for hot die forging on GCM and crank hot forging presses.
Areas of application for hexagonal rolled metal products:
mechanical engineering;
Construction industry;
Shipbuilding and aircraft industry;
Production of medical equipment;
furniture industry;
Manufacturing of food equipment;
Mining industry.
The steel hexagon has found its application in many areas of industry, but most often it is used in construction. Hexagonal rolled metal can be used as composite metal structures, frames, load-bearing elements, decorative structures and fences.
The assortment of calibrated hexagons is made in accordance with GOST 1051-73 from carbon and nickel-containing steel by cold rolling. This method of production of a hexagon ensures high accuracy of its section. Depending on the processing method, there are several types of this product:
Matte. It undergoes minimal processing, but still has a high-quality smooth surface.
Sanded. To achieve even greater accuracy, grinding is carried out on the machine.
Mirror. The exceptional quality and precision of the product is achieved by grinding to a brilliant state.
This type of rolled metal lends itself well to significant loads and welding, is resistant to high temperatures and has high performance characteristics. A calibrated hexagon can also be made from steel grades such as alloyed, heat-resistant, tool, spring-spring, etc.
