Appearance of a set of hexagons

All types of hexagons are based on an iron rod. It is on it that the first impulse of torque falls, and therefore its strength is of great importance.

The raw materials used for its production must be reliable, resistant to destruction, and suitable for long-term use.

Size range, weight and basic geometric parameters

The size/number of a hexagonal section is determined by the diameter of the circle d inscribed in it (d is equal to the distance between parallel edges - “key size”). According to the GOCT 2879-2006 assortment, the minimum permissible size is d=8 mm, maximum d=103 mm.

Step size range of hexagonal rolled products:

for d from 8 mm to 20 mm, the step is 1 mm;
d from 20 to 30 mm, step 0.5 or 1 mm;
d from 30 to 40 mm step 1.5 or 0.5 mm;
d from 40 to 50 mm the pitch can be: 4.5 mm, 2 mm, 2.5 mm, 3 mm, 0.5 mm;
d from 50 to 103 the step is 1, 2 or 3 mm.

The weight of a linear meter of a hexagon can also be calculated with greater accuracy using one of two formulas:

on the side of the hexagon M = 0.007850×a²×(3√3)/2 = 0.020395×a² (kg/m), where a is the side of the hexagon in millimeters;
along the radius of the inscribed circle (half the distance between any two parallel faces) = 0.007850×r²×2√3 = 0.027193×r² (kg/m), where r is the radius of the inscribed circle in millimeters.

For example, for hexagonal rolled steel No. 10, the weight of a linear meter (according to formula No. 2) is equal to:

0.027193×52 = 0.679825 kg (the rounded table value according to the product range is 0.680 kg).

The side length a(mm) of the hexagon is calculated by the formula:

a = d (mm)/√3 = d (mm)/1.73205; for example, the side of hexagonal roll No. 10 will be equal to: 10÷1.73205 = 5.8 mm.

Steel hexagons - characteristics and assortment according to GOST

Steel hexagon is a type of rolled metal. Produced by hot rolling from round billets. To improve surface quality and dimensional accuracy, hot-rolled products are calibrated.

Most often, hexagonal rolled steel is used for the manufacture of fasteners - bolts, nuts, studs. Fasteners are usually heat treated.

Depending on the planned area of operation, carbon steels of ordinary quality and high-quality, tool, low-alloy or corrosion-resistant steels are used for the manufacture of these products.

Hexagon dimensions

The defining dimensional parameter - the nominal diameter of a circle inscribed in the cross section - is determined in millimeters. The range of hot-rolled steel hexagons is regulated by GOST 2879-88 and covers the range of section sizes - 8-103 mm.

Products are sold in rods with a length of 2-6 m, at the request of the customer - from 1.5 m. By agreement with the consumer, rolled products with a diameter of up to 20 mm can be supplied in coils. According to the degree of rolling accuracy, products are distinguished: B1 - increased accuracy, B1 - normal accuracy.

Calibrated steel hexagon is produced in accordance with GOST 8560-78, the range of section sizes is 3-100 mm. Before calibration, to reduce specific loads, the workpieces are subjected to phosphating. Such metal products are usually used in precision engineering.

Weight of steel hexagon

To determine the mass of a batch, you need to know the weight of 1 linear meter, which can be calculated independently using a formula or determined from a table. In both cases, the average steel density value of –7850 kg/m3 is used in the calculations.

M = 0.0067983*a2 , where:

M – mass of 1 linear meter, kg;

a is the diameter of a circle inscribed in a hexagon, mm.

Advantages of steel hexagon

Hexagon

is a product of the metallurgical industry, which looks like a kind of rod with six edges. The scope of its application is wide, it includes construction and various industrial sectors. It is used to make bolts, nuts, hardware and other metal parts. The hexagon is used to assemble various mechanisms.

The division into types is carried out in accordance with its qualitative characteristics, namely:

•

Depending on the steel grade

•

According to the presence of chromium, copper and nickel in it

•

According to the processing method

(heat-treated, untreated, cold-hardened)

•

Depending on the production method (forged, hot rolled)

•

By type of further processing

•

By chemical composition (high-quality, high-quality)

Production of hexagons from steel

Making hexagons

regulated by European standards DIN 1015-1972. The diameter of the hexagon is the diameter of the inscribed circle. The materials used are different. It can be alloyed, high-alloyed, or carbon steel.

It is produced by so-called rods, their length is designated as measured, unmeasured, multiple measure and limited measure. Rods with a length of one and a half meters but no more than two are considered remnants. The standard length is from 2 to 6.5 meters.

However, upon individual order it is possible to increase the length of the rods to 12 meters. To display the mass of rolled products, as well as to determine permissible deviations, special reference books and tables have been developed. You can calculate the mass yourself, knowing the density of steel, which is 7.85 g/cm³.

When marking hexagons, numerical indicators of length, cross-section, steel size, and production method are used.

Hexagons are resistant to corrosion, have high strength, and are easy to weld. The choice of type of this type of product will directly depend on the purpose and scope of application.

According to GOST 2879-88 , the hexagon is made of carbon, alloy, high-alloy hot-rolled steel, and has dimensions (inscribed circle diameter) from 8 to 100 mm. GOST 8560-78 applies to calibrated steel with a hexagonal section ranging in size from 3 to 100 mm. According to the rolling accuracy, hexagonal rolled products are divided into categories: Rolled products are made from 2 to 6 m in length, measured length, multiple measured length and unmeasured length. At the consumer's request, rolled products are manufactured in lengths from 1.5 to 12 m. Steel hexagon and stainless hexagon have a certain symbol. For example, a calibrated hexagon with a section size of 19 mm, length 10 m, steel grade st45 GOST 8560-78 is designated as follows: Hexagon caliber 19 st45 L=10 GOST 8560-78. B - high-precision hexagon;

The weight values of a linear meter and the number of meters per ton in the table are indicated for reference. Calculations are made based on the nominal dimensions of the profiles. The specific gravity of steel is taken to be 7.85 g/cm3. The actual weight of the profiles, taking into account the tolerances provided for by GOST 2879-2006, may differ significantly from the calculated one.

In recent years, the price of rolled metal products has been changing dynamically, which makes it difficult to publish current prices that correspond to the present moment. In addition, the price for a hexagon is determined individually, depending on the order volume and other delivery conditions.
