Introduction to Marine Steel Plate Marine steel plate is classified as medium and heavy plate, which is a hot-rolled steel plate produced according to the requirements of the construction code of the classification society for the manufacture of ship hull structure. First of all, good toughness is the key requirement of marine steel plate, in addition, it is required to have high strength, good corrosion resistance, welding performance, processing and forming performance and surface quality. In order to ensure quality and ensure sufficient toughness, the chemical composition of Mn/C is required to be above 2.5, and there are strict requirements for carbon equivalent, and it is produced by a steel mill approved by the ship inspection department.

GBT712-2022 "Structural Steel for Ships and Offshore Engineering" standard includes:
