According to the minimum yield point, the marine grade steel plates / hull steel plates can be divided into general strength hull steel plates and high strength hull steel plates. Among them, A131 marine grade A ms steel plate, A131 grade B hull steel plate, AH36 hull structure steel plate, hull steel DH36, EH36 hull steel plate etc. are most widely used. FH32 ship construction steel plate, FH36 offshore platform steel plate, hull structure steel AH40, DH40 offshore platform steel plate, EH40 plate strength are high and are mainly for special purpose.
The main steel grades of hull steel plates:

Marine grade hull steel plates are used to manufacture the hull structure of ocean going, coastal and inland navigation ships. Marine grade hull steel plates is required to have certain strength, toughness, low temperature and corrosion resistance, and good welding performance.
