overall — IT;

for hot forging of nuts — GSHG;

for cold forming of nuts HSG;

— accuracy rolling:

thickness:

high — БТ1, BT2, БТ3;

normal — VT1, ВТ2, VT3;

width:

high — БШ1, БШ2, БШ3;

normal — ВШ1, ВШ2, ВШ3;

length:

dimensional — MD;

measuring with non-standard length — MD1ГОСТ 103-2006 Прокат сортовой стальной горячекатаный полосовой. Сортамент;

dimensional — CD;

dimensional with random length — КД1ГОСТ 103-2006 Прокат сортовой стальной горячекатаный полосовой. Сортамент;

random — ND;

limited within the random — OD;

limited from the random length — EA1ГОСТ 103-2006 Прокат сортовой стальной горячекатаный полосовой. Сортамент;

rolls — RD;
________________
ГОСТ 103-2006 Прокат сортовой стальной горячекатаный полосовой. СортаментIn the supply of rental with dimensional random length (MD1) dimensional with random length (КД1) and bounded by random length (EA1) is allowed rental of random length not more than 5% of the batch weight.

— limit deviations for the length of rental and multiple dimensional measuring length groups, DB and VD;

— the blunting of the angles in BU and WU;

— the requirement to camber:

high — as;

high — BS;

ordinary — sun;

— flatness:

particularly high — AT;

high — PV;

normal — MON.
