The marine steel plate, that is, the structural steel for the hull, is divided into general strength structural steel and high strength structural steel according to its minimum yield point.
marine steel plate refers to the hot-rolled steel plate used to manufacture the hull structure produced in accordance with the requirements of the classification society's construction rules.
The general-strength structural steels in the standards of China Classification Society are divided into four quality grades: A, B, D, and E (namely CCSA, CCSB, CCSD, CCSE); the high-strength structural steels in the standards of China Classification Society are three Intensity levels, four quality levels.
The main classification society rules for marine steel plates are:
China CCS
American ABS
German GL
French BV
Norwegian DNV
Japanese NK
British LR
Korea KR
Italy RINA
Russia RMRS
