GB/T 16270 Q550 include the representative of the yield strength of the Chinese phonetic alphabet, yield strength values, quality grade symbols: “Q” represents the steel yield strength of the "bend" and the first letter of the Chinese phonetic alphabet; “550” represent the yield strength value in unit MPa. “D” represent the quality grade for the D-level (grade is divided into C, D, E). Q550 High Strength Plate is mainly used in important (low temperature) high-strength structural parts, engineering machinery, mining, steel structure, etc.
