3.Terms and Definitions
The terms and definitions defined in GB/T 1591 apply to this document.
4.Brand designation method
The steel grade is composed of the first letter of the Chinese pinyin for "yield strength," the specified minimum upper yield strength value, and the Chinese pinyin for "wind tower."
It consists of five parts. the first letter of the name, the delivery status code, and the quality grade symbol (B, C, D, E, F).
Note. When the delivery condition is hot-rolled, the delivery condition designation AR or WAR is usually omitted; when the delivery condition is normalized or normalized rolled, the delivery condition designation is...
The code N represents the delivery condition; when the delivery condition is thermomechanically rolled (TMCP, TMCP tempered), the code M represents the delivery condition; when the delivery condition is quenched and tempered...
In this case, the delivery status code is represented by Q.
Example. Q355FTND, where.
Q --- the first letter of the Chinese pinyin for yield strength;
355 --- The specified minimum upper yield strength value, in megapascals (MPa);
FT --- the first letters of the pinyin for "wind tower";
N --- Delivery condition is normalized or normalized rolled;
D --- Quality grade is D.
When the steel plate is required to have properties in the thickness direction, the grade representing the properties in the thickness direction (Z direction) should be added after the grade specified above.
The symbols (Z15, Z25, Z35), such as Q355FTNDZ15.
