1.DH36: D represents quality grade D, H refers to high-strength building materials, 36 is the maximum pressure resistance, Z is Z-tensile. It is structural steel for high-strength ship hulls. Shipbuilding steel generally refers to the steel used for hull structure, that is, the steel produced according to the requirements of the classification society construction code for the manufacture of hull structure. Often used as special steel ordering, production, sales, generally including ship plate, steel and so on.
2. DH36 ship plate for high strength ship plate, China Wuyang Iron and steel enterprise production, according to user needs to produce different national standards of Marine steel, such as the United States, Norway, Japan, Germany, France, etc., its specifications are as follows:

8. DH36 variety specifications
According to its small yield point, the structural steel used for ship hull is divided into strength classes: general strength structural steel and high strength structural steel.
China Classification Society standard general strength structural steel is divided into: A, B, D, E four quality grades; The high strength structural steel according to the China Classification Society specification has three strength levels and four quality levels:
A32 A36 A40
D32 D36 D40
E32 E36 E40
F32 F36 F40
