Q400GMDR grade expression method

The grade of steel is defined by the initial character of the word "" in yield strength, the value of minimum service strength (specified plastic elongation strength), the words "high" and "manganese" representing high manganese, and the "low" and "capacity" of cryogenic containers Example of the three-part composition of the first letter of the word Chinese pinyin, Q400GMDR. Among them,

Q-11 flexion strength of the character "Qu" in the first letter of Chinese pinyin GM-"high manganese" in the "high" and "manganese" in the Chinese spelling initials

DR-"low capacity" in the word "low" and "rong" in the first letter



of Chinese pinyin 400- The specified small service strength, the unit is Pa, and the MP is the specified plastic elongation strength R.Q400GMDR The grade and chemical composition (melting analysis) of steel shall comply with the provisions of the following table.



3.2 In order to improve the performance of Q400GMDR steel, other alloying elements other than those in Table 1, such as Ni, Mo, Nb, V, Ti, Al, etc., can be added, and Ni ≤ 1.0%, Mo ≤ 0.30%, Nb+V+Ti≤0.30%, Alt ≤ 0.10%, and indicate the corresponding element content in the quality certificate. When Ni ≥ 0.30%, Cu can be lower than 0.30%
