GBT16270 Q550D High strength structural steel plate is yielded in the 550 high-strength plate. D is 0 degrees on behalf of the impact of qualified. Q550D steel sheet which: Q-steel yield strength of the "bend" the first letter of the Chinese phonetic alphabet; 550 - yield strength Value, unit MPa; D-quality grade for the D (grade is divided into C, D, E).

When the Q550D steel sheet is required to have a thickness direction property, a symbol representing the thickness direction (Z direction) performance level is added to the predetermined grade, for example, Q550D-Z15. Q550D steel is mainly used in important (low temperature) high-strength structural parts, engineering machinery, mining and other steel structures.
