Ni is the basis.
According to TU 14-131-1042-2008, the chemical composition is given for an alloy of the brand KhN58MBYU-ID (EC171-ID, VZH159-ID). Magnesium, boron, yttrium and lanthanum are introduced into the metal by calculation and chemical analysis are not determined. In the finished metal, deviations from the chemical composition of molybdenum ± 0.10%, niobium ± 0.10% are allowed.

| Macrostructure and pollution |
The macrostructure of bars-prescisely on the other 14-131-1042-2008 should not have shrinkage, bubbles, cracks, inclusions, delaminations, visible without using the magnifying devices. On the surface of pellet-prescisely should not be captured, cracks, cavities. Local defects should be removed with gentle scraping. The depth of Stripping shall not exceed the negative limit deviation, measured from the nominal size. Allowed without Stripping some small risks, dents, Rabina within the negative deviations measured from the nominal size. |
| Particularities of production of goods |
Bars-pressestelle on the other 14-131-1042-2008 are supplied without heat treatment or heat treated (quenched) state and regime: Hardening in air, 1080-1120 °C. |
