3 tensile Test

3.1 General situation

The tensile test is carried out according to ISO 6892 at ambient temperature.

3.2 Type test sample

Test samples are taken according to ISO 377, using the full cross-section, i.e. they must be in rough parts of the wire.

3.3 Preparation of test samples

Test specimens should be straightened with care to prevent damage, according to ISO 377 and ISO 6892.

3.4 cross-sectional Area

For the calculations in tension using the actual dimensions of the test samples. Use the nominal dimensions, if specified in the product standard or order. For non-circular wire cross-section source cross-section can be determined by the weight of wire of known length and its density.

3.5 Method of capturing test samples

When testing small diameters (less than or equal to 1 mm), it is recommended to roll the ends of the wire around a round rod or disc and pin in order to avoid breakage of wire in the area of capture.

3.6 tensile Test of the associated wire

Tensile tests of the wire is associated a simple node in the middle of the test piece, carried out according to ISO 6892.

Test 4 simple torsion


Tests for simple torsion is carried out according to ISO 7800. In the case of primary fracture it is necessary to re-test in accordance with ISO 404. If possible, re-test is carried out at a speed of (1±0,2) revs/s.

If necessary, the characteristics of rupture when tested in torsion is determined on the basis of Table 1.

Note: For a wire of small diameters it is sometimes impossible to distinguish between the types of gap, described in table 1 (the so-called 2b and 3b).

5 Test for inflection


The test bend is carried out according to ISO 7801, with the following amendments for automatic counters.

If the test stand is equipped with an automatic counter running on the limit switches, the first bend of 90° counts as one bend and the second bend is 180° in the opposite direction. The number of excesses believe the last number received prior to destruction.

6 Test winding


The test winding is carried out according to ISO 7802. This test may be performed to assess plasticity, adhesion or ability of the wire to form a rebellion, as set out in the relevant standard for the product.

7 bend Test


When tested in bending the wire bend around a mandrel of a certain diameter for a fixed angle in one operation with the ambient temperature. Details are given in the relevant standard for the product.

8 Test for alternating torsion


Tests for alternating torsion with the direction change carried out in accordance with ISO 9649 with the following addition.

Tests are conducted to detect surface defects and to assess plasticity.

9 compression Test

9.1 Appointment

The test is intended for detection of surface defects. This test is not carried out for wire diameters less than 4.0 mm.

9.2 Principle

Direct test sample wire, equal in length to 1 (or 1.5) to the diameter of the wire is cut so that the slices are at right angles to the axis of the wire. The test sample is placed on a flat surface of a test stand for compression and compressed at room temperature in the direction of the axis of the wire to a specified percentage of its total length. The compressed test sample is examined for surface cracking. The degree of acceptability is fitted as standard to the product.

10 Test for deep etching

10.1 Appointment

Test deep etching is carried out for detection of surface defects.

10.2 the Principle

Cool the test piece deformed by the extractor, degreased, as necessary, by washing and drying. High carbon steel is carried out for stress relief from the test sample by heating and aging at a temperature of from 400 °C to 500 °C for 15 min and subsequent cooling at ambient temperature before etching. With the exception of the samples with a diameter greater than 5.00 mm and the samples with annealed structures, the test piece immersed in a mixture consisting of 50% by volume of concentrated hydrochloric acid and 50% by volume of water at a temperature of at least 60 °C for a period equal to 2 for every 0.025 mm of diameter, but not more than 5 min. the Test samples with a diameter greater than 5.00 mm and the samples annealed structures are allowed to be immersed in the solution for no more than 10 min.

The test sample was examined for surface defects. To determine the depth of defects they are filled in, the difference in thickness before and after filling in the register as the depth of the defect. For the final evaluation of the defects used optical microstructural analysis.

11 hardness


Hardness test carried out in accordance with ISO 6506−1, ISO 6507−1 or ISO 6508−1 as set out in the product standard or order. It is desirable to make a distinction between surface hardness, core hardness and through hardness.

Note — there is no relationship between hardness and tensile strength.

12 Determination of hardenability


The test samples for determining hardenability is heated in a neutral or reducing atmosphere furnace to the quenching temperature set for the type of steel, and kept at this temperature until complete austenization.

The samples were then removed from the furnace and immediately quenched in the quenching oil for severe to complete alignment of the temperature. Quenching oil for severe conditions should have a temperature of (50±10)°C should be sufficient and well-mixed and, together with the speed of the dive must ensure that the test samples of the temperature of the quenching oil without significant delay. Then subjected to the hardness test in accordance with section 11 respectively prepared test sample. It is desirable to distinguish between core hardness and through hardness. In case of disagreement it is necessary to apply to the value of Jomini hardenability in the initial billet of a particular steel.

13 a Test of fatigue (in bending with rotation and axial load)


Tests used for the wire are tested for fatigue under axial load or a fatigue test at a bending with rotation. In these tests the possible variability. Therefore, you must be very cautious in interpreting the results of one test against the results obtained with another test. The complexity of the interpretation that the special instructions given in the relevant standards for the product.

14 Dimension of the set of turns of wire

14.1 General provisions

14.1.1 the Set of turns of wire is characterized by a form of coil wire unwound from riot or from the drum and freely lying on a flat horizontal surface or freely suspended on the rod, as installed in one of the tests described below. On a flat surface the ends of the spiral can lie down together (closed coil) or separated (open coil).

Note — For this part of this standard the terms «riot», «drum», «spool» and «bobbin» are synonymous.

14.1.2 rebellion cut off enough wire to get several full turns of wire (one for each test), while the absence of bending and damaging the wire (figure 1).

Figure 1 — Sampling of wire

ГОСТ Р ИСО 22034-1-2013 Проволока стальная и изделия из нее. Часть 1. Общие методы испытаний


and Cut a few turns of wire from the rebellion and from the received sample cut off one coil for measurement.
