Q500D Q550D High Strength Steel
Q500D is a high-strength structural steel plate. The implementation standard of Q500D steel plate is: GB/T 16270-2009 special technical conditions.
Grade naming method: The steel grade consists of the first letter of the Chinese pinyin representing the yield strength, the minimum yield strength value, and the quality grade (C, D, E, F), which are arranged in order. Q---the first letter of the Chinese pinyin of the word "qu" for the yield strength of steel; 500---the value specifying the minimum yield strength, in MPa; D---the symbol of quality grade.
Q550D is a grade steel with a yield strength of 550mpa. Is a higher strength low alloy steel, Q550D steel plate is a high strength steel plate with low welding crack sensitivity. The first letter of the Chinese pinyin of "Q" in the yield strength of "Q" steel; "550": the yield strength of the steel plate is 500, in MPa; "D": indicates that the quality grade of the steel plate is D (grades are divided into C, D, E ).
