Q370qC/D/E steel plates for bridge

Q370qC/D/E steel plates are bridge, which are grade Q370qC, Q370qD, and Q370qE. These are low alloy high-strength steels, steel grades for bridges. The first letter of the Chinese pinyin of the "yin" of the Q bridge steel yield point; 370 yield point value. The unit is Mpa; the first letter of the Chinese pinyin of the "bridge" character of q bridge steel; the quality grades of C, D and E are C grade.
