Grade Q460C steel plate Introduction by the representative of the Chinese phonetic alphabet yield strength, yield strength values, composition quality rating symbols into three parts, and Q420C similar example: Q460C. Where: Q- yield strength steel, "Qu" Pinyin first letter of the word; 460- yield strength value, the unit MPa; C- quality level D grade (class is divided into C, D, E). When the demand side need steel sheet has a thickness direction performance, after the grades specified above, plus representatives of the thickness direction (Z direction) performance level of symbols, for example: Q460CZ15. Wugang conventional product delivery status: ≤ 50mm hot-rolled or controlled rolling, 51-60mm controlled rolling or normalizing,> 60mm normalizing.
