3.7. The control for non-metallic inclusions for steels specified in paragraph 2.11 is carried out on 6 samples from the melting of the half-method GOST 1778 by the Sh4 method.

3.8. The magnetization of the cast sample is determined according to the method of the billet supplier.

3.9. Inspection for macrostructure and ferrite base content may not be performed, but must be guaranteed by the supplier within the scope of this specification.

3.10. TCLE is determined according to GOST 14080.

3.11. The test of the survivability of an alloy with a high electrical resistance is carried out by the wire manufacturer in accordance with GOST 2410 on the ingots specified by the manufacturer of the billet. Controls survivability on at least one smelt from one smelting campaign. The number of heats included in one smelting campaign is determined by the company to manufacture the blanks. One smelting campaign can include smelts smelted with the use of one batch of microalloying additives that determine the required survivability (ferrcerium, ferrosilicon, etc.).

When shipping the workpiece, the document on quality indicates: «Complies with GOST 12766.1» or «Complies with GOST 12766.2».

The results of survivability tests are reported by the wire manufacturer to the manufacturer of the workpiece no later than three months after the receipt of the workpiece.

The wire manufacturer conducts durability tests on no more than 30 samples per month.

3.12. Ultrasonic testing is carried out according to the manufacturer’s method.

4. Marking, packaging, documentation and transportation

4.1. Each workpiece is marked. Marking is applied on one end of the workpiece by stamping the steel grade or its heat number index. If necessary, the number of the ingot and the letter of the workpiece are applied.

Steel smelted in electroslag installations is additionally marked with the letter «Ш», in vacuum arc installations — «VD», in vacuum induction furnaces — «VI», and other designations depending on the method of smelting.

P.16
TU 14−1-1213−75

A workpiece with a square side of 36 and 38 mm is allowed to be branded on the side surface in the order indicated above.

4.2. The workpiece is delivered in bundles.

4.3. Other requirements for acceptance, labeling, packaging, transportation and storage in accordance with GOST 7566.

4.4. The mass of a batch of workpieces must be at least 1.5 tons, unless a lower mass is specifically specified in the order.

The mass of a batch of billets made of electroslag metal, vacuum-arc remelting must be at least 0.25 tons.

The mass of a batch of billets from metal of induction and vacuum-induction smelting must be at least 0.14 tons.

The mass of a batch of workpieces made of metal of electron-beam, plasma-arc and duplex processes should not be less than 0.05 tons.

Note: Contract prices apply to workpieces.
