Fe is the basis.
According to TU 14-159-186-89, According to TU 14-1-2903-80 the chemical composition is presented for steel grade 06H15N6MVFB-SH (VNS16-Sh). Deviations in chemical composition are allowed: carbon +0.010%, nickel ± 0.010%, silicon +0.10%, manganese +0.10%, molybdenum ± 0.10%, chromium ± 0.10%, for tungsten ± 0.10%, for niobium + 0.010 / -0.020%, for vanadium + 0.010 / -0.020%.
For limited use, the content of residual elements should not exceed: copper - 0.20%, titanium - 0.050%. The content of the residual elements can not be determined. The steel is marked 06Х15Н6МВФБУ-Ш (ВНС16У-Ш).

Macrostructure and pollution	The macrostructure of the workpiece on the other 14-1-2903-80 when checking for cross etched templeto should not have shrinkage, blistering, delamination, foreign metal and slag inclusions are visible without using the magnifying devices. Allowable defects of the macrostructure shall not exceed, in points: Central porosity ≤ 1,0; - point nonuniformity ≤ 1,0; - exudation square ≤ 1,0; - layer-by-layer crystallization and the light circuit ≤ 3,0. Pollution steel non-metallic inclusions in points: - oxides of stroke (OS) ≤ 2,0; - oxides of point () ≤ 2,0; - silicates fragile (CX) ≤ 1,0; - silicates plastic (SP) ≤ 1,0; - silicates, non-deformed (SN) ≤ 2,5; sulphides (S) ≤ 1,0; - nitrides stroke (NS) ≤ 1,0; the nitrides of the point (NT) ≤ 1,0.
Particularities of production of goods	On the other 14-1-2903-80 billet is supplied in the annealed or tempered condition, stripped in accordance with the agreed standard. Clan or extract ratio of the workpiece must be not less than 4.5.
