Reprinting. June 2011

1. This standard specifies the grades of Nickel and Nickel low-alloyed alloys pressure treated and are intended for the manufacture of semi-finished products used in electronics.

The standard fully complies ST SEV 1257−78 and establishes requirements for the chemical composition of Nickel and Nickel low-alloyed alloys of Nickel grades: NK0,04, MWF, HB3, Nv3v, Nvmg3−0,08 in, Nka0,07 Nka0,13.

Compliance with the requirements of the standard of the CMEA requirements of this standard are given in Appendix.

2. Brand and chemical composition of low alloy Nickel and Nickel alloys shall be as specified in table.1 and 2.

Table 1

Nickel

Notes:

1. The designation marks the letter «V» means vacuum melting, «V» — vacuum-induction.

2. The oxygen content is specified for Nickel bullion.

3. The sum of mass fractions of impurities of lead, zinc, cadmium, arsenic, antimony, bismuth and phosphorus should be no more than the Nickel brand Np0jevi, Np1jev — 0,007%.

In Nickel brand NP2JE obtained by vacuum melting, mass fraction of lead, cadmium, arsenic, antimony, bismuth, phosphorus should be not more than 0.001% of each element of zinc, less than 0.003%.

4. Mass fraction of cobalt for grades of Nickel Np0jevi, Np1jev and NP2JE was optional prior to 01.01.1982 city

Table 2

Low-alloy Nickel alloys

Notes:

1. The oxygen content is specified for the alloys in ingots.

2. In grades NK0,2JE and Nmg0,1, obtained by vacuum melting, mass fraction of zinc should not be more than 0,002% mass fraction of tin, lead, cadmium, arsenic, antimony, bismuth and phosphorus — not more than 0.001% for each element.

The designation marks NK0,2JE and Nmg0,1 in this case, add a letter «b».

3. In the Nickel-magnesium vacuum melting mass fraction of zinc may be no more than 0,004%.

4. The alloy grade Nmg0,1 allowed mass fraction of magnesium is not more than 0.15%, silicon not more than 0.02%, sulphur: not more than 0.005%.

5. The alloy grade NK0,2JE when applied for the manufacture of pipes is allowed the mass fraction of manganese — not more than 0.03%, sulphur not more than 0.005%, cadmium, antimony, bismuth, phosphorus and tin — not more than 0.001% for each element.

6. At the request of the consumer grade Nv3v must be manufactured with a mass fraction of magnesium 0,015−0,04%.

7. Mass fraction of cobalt alloys for grades NK0,2JE, Nmg0,1, Nmg0,05v and Nmg0,08v and mass fraction of aluminium alloys for grades NK0,2JE and Nmg0,1 was optional prior to 01.01.1982 city

3. Rounding of the results of chemical analysis carried out according to ST SEV 543−77.

4. The mass fraction of the sum of Nickel and cobalt determined as the difference between 100% and sum of mass fraction of alloying elements and impurities determined.
