Notes


1 cross-sectional Area and weight of 1 m of length of rental is calculated based on nominal dimensions. When calculating the mass of 1 m length of the rental, the density of steel is equal to 7.85 g/cmГОСТ 2590-2006 Прокат сортовой стальной горячекатаный круглый. Сортамент. Weight of 1 m of length of rental and the cross-sectional area of hire are reference values.

2 By agreement between manufacturer and consumer (the agreed specifications) hire manufacture intermediate sizes with extreme deviation to the nearest smaller in diameter.

3 For rolled diameter up to 9 mm inclusive, in coils manufactured at mills that are not equipped with finishing blocks, allowed tolerances for diameter ±0.5 mm (B4).

2.2.1 hire with precision rolling A2 and B2 (table 1) allowed to produce with plus extreme deviation equal to the amount of the limit deviation for diameter (A3 and B3).

2.3 By agreement between manufacturer and consumer (the agreed specifications) is allowed to produce rolled stock with diameter more than 270 mm to 300 mm, inclusive, with limit deviation of ±6.0 mm over 300 to 330 mm inclusive, with limit deviation of ±7.0 mm.

2.4 By agreement between manufacturer and consumer (the agreed specifications) rental produce with plus the limit deviation for diameter (B5) shown in table 2.
