Notes:

1. At the request of the consumer, calibrated hexagonal rolled products are manufactured in other sizes not specified in tab. one . Limit deviations in this case must comply with the standards established for the nearest larger diameter.

2. The cross-sectional area and linear density of calibrated hexagonal rolled products are calculated from the nominal size. The density of rolled products is taken equal to -7.85 g/cm 3 .

3. For rolled products from high-alloy steel grades and alloys subjected to heat treatment and etching, limit deviations in size are set at 30% more than the quality h 12.

3. Rolled calibrated hexagonal is produced in bars. At the request of the consumer, rolled products are produced in coils.

(Changed edition, Rev. No. 1, No. 2).

4. Depending on the purpose, the bars are made:

measured length;

multiple measured length;

random length with a remainder of up to 10% of the mass of the batch;

limited length within unmeasured.

The remainder is considered to be bars with a length of at least 1.5 m.

5. Bars are made in lengths from 2 to 6.5 m. At the request of the consumer, bars are made in large lengths.

(Revised edition, Rev. No. 1).

Items 6, 7 are excluded, Amend. No. 1).

30 mm - with a length of bars up to 4 m;

50 mm - with a length of bars over 4 m.

9. The curvature of the bars should not exceed the values ​​specified in Table. 2.

10. Twisting of bars per 1 m of length (Fig. 2) should not exceed 3°.

(Revised edition, Rev. No. 1).

11. The cut of the bar must be at right angles to its longitudinal axis. Permissible slant of cut should not exceed:

0,2 a- with the size of bars up to 15 mm;

0,17 a- with the size of bars up to 16 mm;
