According to TU 14-1-2097-77, the chemical composition is presented for the alloy 01Х18Н40М5ГBR-ID (EP753R-ID), melted by the vacuum induction melting method followed by vacuum-arc remelting. In the alloy, deviations in the content of the elements are allowed: for carbon +0.0050%, for silicon +0.10%, for phosphorus +0.0050%, for molybdenum + 0.30%, for nitrogen + 0. 0050%, for boron +0.0030%. Cerium is introduced into the metal by calculation and chemical analysis is not determined. the residual impurity content should be (guaranteed by the manufacturer): cobalt ≤0.010%, copper ≤0.050%, arsenic ≤0.0050%, lead ≤ 0.00050%, cadmium ≤ 0.00050%, tin ≤0.0010%, zinc ≤ 0.0010%, antimony ≤0.0010%, bismuth ≤ 0.00050%, tantalum ≤0.0050%, titanium ≤0.050%. The deviation in the tantalum content is +0.0050%, titanium +0.050%.

Macrostructure and pollution In the macrostructure of the workpiece in the state of delivery should be free of cracks, gas bubbles, subcortical bubbles, turns brown, inclusions, delaminations, traces of shrinkage of the shell, visible to the naked eye. Layer-by-layer crystallization and the square of the increased travelmasti are not rejection symptom. The evaluation of contamination of metal non-metallic inclusions. The norm of non-metallic inclusions by the maximum score: - sulphides ≤ 1.0 points; - nitrides and carbonitrides point ≤ 1.5 points; - nitrides and carbonitrides stroke ≤ 2.5 points. The total number of oxygen inclusions (granules and globules of oxide spinels, silicates and silicate glasses) shall not exceed: a) from 1 to 2 inclusive divisions of the ocular scale in 2 sections - 50 inclusions on 6 sections - 150 inclusions; b) from 2 to 5, inclusive divisions of the ocular scale in 2 sections - 1 for on, - for 6 sections - 3 inclusions; C) larger than 3 divisions of the ocular scale are not allowed.
Particularities of production of goods Tubular billet on the other 14-1-2097-77 made in accordance with the terms of the supply 01-1874-62.
Corrosion resistance Metal forged tube blank on the other 14-1-2097-77 must be able to withstand the test of susceptibility to intergranular attack according to the method of AM GOST 6032.
