4 Designation expression
The designation of steel consists of three parts: the Chinese phonetic initials of "Qu" for yield strength, the specified minimum yield strength (specified plastic extension strength), the Chinese phonetic initials of "Gao" and "Meng" for high manganese and the Chinese phonetic initials of "Di" and "Rong" for low-temperature vessels. Example: Q400GMDR. Where,
