Ship plate is a hot-rolled steel plate used to manufacture hull structure, produced according to the construction specifications of the classification society. Common ship plate materials include CCSA, CCSB, CCSC and CCSD quality grades, which are mainly used to manufacture high-strength ships and marine engineering structures, such as the deck, hull and bulkhead of the ship, with good corrosion resistance and high strength

General strength hull structure steel

General strength hull structure steel is divided into 4 grades: A, B, D, and E. The yield strength (not less than 235N/mm^2) and tensile strength (400~520N/mm^2) of these 4 grades of steel are the same, but the impact energy at different temperatures is different;

High-strength hull structure steel is divided into strength grades according to its minimum yield strength, and each strength grade is divided into 4 grades: A, D, E, and F according to its impact toughness.
