The grade of Q420C steel consists of three parts: Chinese Pinyin letters representing yield strength, yield strength value, and quality grade symbol. among them:
Q—The first letter of the Chinese Pinyin of "qu" for the yield strength of steel;
420—Yield strength value, unit MPa;
D-quality grade is D grade (grades are divided into C, D, E).
When the buyer needs the steel plate to have thickness direction performance, add the symbol representing the thickness direction (Z direction) performance level after the above-mentioned grades, for example: : Q420ND, Q420DZ15.
