1 area of use
This standard applies to granulated heat-resistant nickel alloys designed for the manufacture of critical products.
2 Normative references
This standard uses a normative reference to the following standard:
GOST 5632−72 High-alloy steels and alloys are corrosion-resistant, heat-resistant and heat-resistant. Brands
NOTE — When using this standard, it is advisable to check the operation of reference standards in the public information system — on the official website of the Federal Agency for Technical Regulation and Metrology on the Internet or on the annually published informational index «National Standards», which was published as of January 1 of the current year, and on the corresponding monthly published information signs published this year. If the reference standard is replaced (modified), then when using this standard should be guided by a replacement (modified) standard. If the reference standard is canceled without replacement, then the provision referring to it is applied in the part not affecting this reference.
3 General requirements
The grades and chemical composition of the granulated heat-resistant nickel alloys should be as specified in Table 1.
