These technical conditions apply to a forged flat billet (slab) made of alloyed and high-alloyed steel, as well as steel and alloys with special properties, intended for further hot processing.

The technical conditions also apply to the supply of a slab made of metal smelted by electroslag, vacuum arc remelting, vacuum induction and other new remelting methods, as well as treated with synthetic slags.

1. Range

1.1. In terms of size and permissible deviations, the slab must meet the requirements specified in table. 1.

Table 1

• The ratio of the width of the stopper to its thickness should be no more than 6.

1.2. The ends of the stopper should be cut or chopped off at an angle close to right. The slant of the cut is allowed by more than 10 mm.

1.3. The longitudinal ribs of the stopper must be rounded or knocked down.

3. Test methods, rules of acceptance and documentation

3.1. The stopper is delivered in batches of one heat and one size.
