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.
