Note.
1. The manufacturer is granted the right to supply steel grades Х18Н9, 2Х18Н9, 2Х13Н4Г9, Х23Н18, Х18Н10Т without mechanical tests, while the supplier plant guarantees the properties specified in table. 3.
2. Bars and strips less than 12 mm thick and rods with a diameter less than 16 mm are not tested for impact strength.
3. The option of heat treatment of steel 1X17H2 is specified in the order. If there is no indication in the order, the test is carried out on samples heat-treated according to option II. Upon receipt of unsatisfactory results of testing the mechanical properties according to the II option, repeated and arbitration tests are carried out according to the I option.

PS No. 3−2011 p.28
«1.1. In terms of shape, size and maximum deviations, metal products must meet the requirements:
a) hot-rolled round bars — GOST 2590, standard rolling precision (B1);
The ovality of hot-rolled round bars should not exceed 50% of the sum of the preliminary deviations in diameter.
The curvature of hot-rolled round rods with a diameter of up to 200 mm inclusive must correspond to class II, over 200 mm — must not exceed 0.5% of the length. By agreement between the manufacturer and the consumer, curvature of another class is allowed.
b) hot-rolled square bars:
— square side up to 200 mm inclusive — GOST 2591, normal rolling accuracy (B1), class II curvature. By agreement between the manufacturer and the consumer, curvature of another class is allowed.
— square side from 160 to 250 mm — TU 14−1-4492−88 (at the request of the customer);
c) forged round and square rods — GOST 1133 ;
d) hot-rolled and forged strips — GOST 103, GOST 4405 .
It is allowed to manufacture strips of non-standard sizes: thickness — 50 mm, width — 190 mm, length — 1070 mm. Maximum deviations in thickness — plus 2.5 mm, minus 0.5 mm, in width — plus 5.0 mm, in length — plus 25 mm. «
3. Clause 2.13, sub-clause a). Replace the words: «intergranular corrosion» with «intergranular corrosion resistance».
4. Clause 3.1, sub-clause h). Replace the word «inclination» with «persistence».
5. Clause 3.14 shall be reworded:
«3.14. The test for resistance to intergranular corrosion is carried out in accordance with GOST 6032, AMU method. «6. Appendix 1 «List of ND, which are referenced in the text of the technical specifications.» Replace:
— Appendix number «1» for the designation «A»;— references from GOST 103−76 to GOST 103−2006, GOST 2590−88 to GOST 2590−2006 and GOST 2591−88 to GOST 2591−2006, GOST 6032−89 to GOST 6032−2003 .
