Ni is the basis.
According to OST 1 90230-76, the total content of other impurities (not indicated) should be ≤ 0.30%, the content of each other impurity should be ≤ 0.010%. The total amount of impurities (regulated and other) should be ≤ 0.60%. The deviation of the silicon content within ± 0.10% is allowed, provided that the mechanical properties are observed. In the case of deoxidation of the alloy with titanium, its content is allowed up to 0.15%.

| Macrostructure and contamination |
In the macrostructure of a longitudinal section casting blank OST 1 90230-76 determined on the macrosections or fractures, are not allowed clogging, non-metallic inclusions. Allowed individual gas shell in an amount of not more than 5 pieces with a diameter of not more than 1 mm each, provided the distance between them not less than 10 mm. is Also permitted total porosity, if it does not exceed 10 pores per 1sm2 surface macrolife with a pore diameter of 0.1 mm to 80% and pore diameter up to 0.2 mm is 20% and zonal porosity, if it does not exceed 15 pores per 1 cm2 of the surface of Microlife with pore diameters up to 0.3 mm - 80% and a pore diameter of 0.5 mm - 20%. |
| Microstructure |
The microstructure of cast billets at OST 1 90230-76 must meet the requirements agreed between the supplier and the consumer. |
| Casting |
The surface of the casting blank OST 1 90230-76 should be clean without svertysha, Nikitin, cracks and foreign inclusions. On the surface of casting blanks allowed shell and other minor defects, provided the depth does not display casting-billet beyond the allowance for machining. Casting-billet after trimming the profitable parts should not have a gaseous porosity of the centering rychlosti. Allowed the presence of a small Central rychlosti if it does not display the casting of the billet beyond the allowance for machining. The zonal area of porosity shall not exceed 20% of controlled surface. The monitored area should be located in the area of the finished part. |
