According to TU 14-1-977-74, the chemical composition is presented for steel grade 06H16N15M3K-III. The ratio of niobium to carbon Nb / C should be within the range of 9-13, a reduction in the Nb / C ratio up to 8 is allowed. A deviation of the content of individual elements is possible provided that the remaining requirements of the technical conditions are met: for niobium - plus 0.20%, for carbon - plus 0.010% / minus 0.005%, for silicon - plus 0.20%.

Macrostructure and contamination In the macrostructure of steel on the other 14-1-977-74 controlled 2 treated templeto selected from two workpieces with a diameter of 80-110 mm of each heat, there should be no cracks, gas bubbles, traces of shrinkage, inclusions, niobium crust, delamination, visible to the naked eye. Allowed: - at the Central porosity ≤ 1 point; - at the point of heterogeneity of ≤ 1 point; - phase separation to the square of ≤ 1 point. Layer-by-layer crystallization in the macrostructure of rejection symptom is not. Contamination of metal non-metallic inclusions is tested on 6 samples cut from 2 samples taken from 2 pieces with a diameter of 80-110 mm. In the metal allowed the presence of non-metallic inclusions by the maximum score: - sulphides ≤ 1.0 points, oxides of point ≤ 2.0 points; - oxides of stroke ≤ 2.0 points, silicates, non-deformed ≤ 1.0 points; - nitrides and carbonitrides point ≤ 3.5 points; - nitrides and carbonitrides of niobium stroke ≤ 3.5 points.
Features of production On the other 14-1-977-74 Serebryanka is supplied in heat-treated according to the mode: Exposure at 920-970 °C, for 40-60 minutes, cooling in water or air. Before the heat treatment, the metal must be subjected to drawing with a reduction degree of not less than 20 %. The grain size in points should not exceed 7.
Corrosion resistance Steel on the other 14-1-977-74 must withstand the test of the ICC method AM (24 hours) according to GOST 6032 pre austenization samples at the temperature of 1050-1100 °C with cooling in air or in water and precipitating by heating at a temperature of 650 °C for 2 hours. The test is performed on 2 specimens cut from 2 samples taken from 2 pieces with a diameter of 80-110 mm of each heat..
