The thickness of Marine steel plate is above 20mm

What is the material of Marine steel plate

Planking models AH32, 40 DH32, DH32, DH36, EH32, EH36, etc

AH32 is a Marine steel plate, mainly used in the manufacture of ocean, coastal and inland shipping ships hull, deck, etc. AH32 steel plate belongs to A kind of Marine steel plate, the "A" inside the grade indicates the quality grade of the steel plate, "H" indicates that the steel plate is a high-strength steel plate, and "32" simply and clearly indicates the yield strength of the steel plate. AH32 Marine steel plate has good impact resistance and machinability, and good corrosion resistance. Usually these AH32 steel plates will also carry a front such as BV, AB and other English letters, these letters are short for, indicating the classification society country of the steel plate execution, such as BV/AH32 steel plate is the French classification society standard AH32 Marine steel plate.

The steel plate for shipbuilding must be the same as the classification society of the ship, the steel mill must pass the inspection of the classification society and obtain the product certificate of the classification society, so that the steel plate can be built. The steel plate (ship plate) used in shipbuilding has many types, and in order to improve the utilization rate, the general customized specifications. Models A plate, B plate, A32, A36, D, D32, D36, E, E32, E36 and other types of steel plate.

What is the material of ship steel plate

D36 and DH36 are just different labeling methods of various classification societies, and they are both high-strength Marine steel.

D36 is the US standard, DH36 is the international standard. Marine steel plate refers to the hot-rolled steel plate produced according to the requirements of the classification society construction code for the manufacture of ship structure. Due to the harsh working environment of the ship, the hull hull is subject to chemical corrosion, electrochemical corrosion and corrosion of Marine organisms and microorganisms. The hull is subjected to large wind and wave impact and alternating load. Ship shape makes its processing method complicated and other factors. China Classification Society standard general strength structural steel is divided into: A, B, D, E four quality grades; High strength structural steel has three strength levels and four quality levels: A32 A36 A40 D32 D36 D40 E32 E36 E40 F32 F36 F40, US standard medium and high strength ship plate with "H", Such as AH32, AH36, AH40, DH32, DH36, DH40, EH32, EH36, EH40, FH32, FH36, FH40. Among them, C, D, E grade steel has good low temperature toughness. It can be used in ships, boilers, pressure vessels, oil storage tanks, Bridges, power plant equipment, lifting and transportation machinery and other welding structural parts with higher loads.
