a. In addition to Q345A and Q345B grades, the steel should contain at least one of the refined grain elements Al, Nb, V, and Ti. According to the needs, the supplier can add one or more refined grain elements. The maximum value shall be as specified in the table. When combined, Nb + V + Ti is not more than 0.22%b. For Q345, Q390, Q420 and Q46O grades, Mo + Cr is not greater than 0.30%c. When Cr and Ni of each grade are used as residual elements, the content of Cr and Ni should not be greater than 0.30%; when it is necessary to add, the content should meet the requirements in the table or be determined by the supplier and the buyer through consultation.d. If the supplier can ensure that the nitrogen content meets the requirements in the table, the nitrogen content analysis may not be performed. If Al, Nb, V, Ti and other alloy elements with nitrogen fixation are added to the steel, the nitrogen content is not limited. The nitrogen fixation content should be specified in the quality certificate.
e. When using full aluminum, the total aluminum content Alt ≥ 0020%. |

a. Allowable adjustment range of heat treatment temperature listed in the table: quenching ± 15 ℃, low temperature tempering ± 20 ℃, high temperature tempering soil 50 ℃.b. In the tensile test, transverse or longitudinal samples can be taken. In case of disagreement, the longitudinal sample is used as the basis for arbitration.c. Boron-containing steel can be normalized before quenching, and the normalizing temperature should not be higher than its quenching temperature.
d. Delivery according to a set of data specified by the demander. When the demander has not specified, delivery can be made according to any of the data. e. The first quenching of titanium steel with Ming Meng can be replaced by normalizing. f. Isothermal quenching at 280 C ~320 C. g. In the tensile test, if Rel cannot be measured, Rp0.2 can be measured instead of Rel. |
