CCS 690 series is structural steel for ships and marine engineering, divided into four quality grades: A, D, E, F, namely AH690, DH690, EH690, FH690, H is high-strength building materials, and 620 is the lower yield strength.
The
GB711-2011 standard is used in the manufacture of sAH690, DH690, EH690, FH690 steel plates with a thickness of not more than 150mm for navigating ships, fishing boats and marine engineering structures in ocean, coastal and inland waterway areas.
The grades are: A, B, D, E, AH32, DH32, EH32, FH32, AH36, DH36, EH36, FH36, AH40, DH40, EH40, FH40, AH420, DH420, EH420, FH420, AH460, DH460, EH460, FH460 , AH500, DH500, EH500, FH500, AH550, DH550, EH550, FH550, AH620, DH620, EH620, FH620, AH690, DH690, EH690, FH690
AH690, DH690, EH690, FH690 ship plates are high-strength ship plates, which can be produced by Wuyang Steel Plant in China, and can produce ship steels of different specifications according to user needs, such as the United States, Norway, Japan, Germany, France, etc., and its classification society certification .
CCS AH690 ship plate is a structural steel with high strength and high strength for hull. Shipbuilding steel generally refers to steel for hull structure, which refers to the steel produced in accordance with the requirements of the classification society for making hull structures.
