Notes:

1. Option thermal treatment of samples indicated in the order, and in the absence of instructions is selected by the manufacturer.

2. Mechanical properties of bars in the transverse samples is determined for bars with diameter 100 mm and more. For bars with a diameter from 80 mm to 100 mm determine only toughness in the transverse samples of type 11 according to GOST 9454. The axis of the specimen shall be held at a distance of ½ of the radius from the surface of the rod.

g) to determine the mechanical properties (tensile tests and impact bending) for two samples from different bars in the batch for each type of test.

3.4. Macrostructure of bars checking for GOST 10243 bars for cross sections up to 140 mm in the finished profiles, for large cross sections can be control samples or reforged perinatalnyj to the size of 120−140 mm.

3.5. Pollution steel non-metallic inclusions test method or Ш4 SH1 (at the supplier’s discretion) according to GOST 1778.

3.6. Tensile test carried out on cylindrical samples five times the length according to GOST 1497. Test for impact strength is carried out according to GOST 9454- - the samples of type 1 and 11. Sampling for mechanical tests according to GOST 7564 subject to note 2 to table 2 of this specification.

3.7. With the repeat testing of mechanical properties determine all the characteristics of strength and plasticity under these technical conditions, regardless of the outcome of initial testing.

In case of unsatisfactory results, re-testing any of the sample batch is rejected.
