AH36 steel plate is normal temperature steel and DH36 steel plate is low temperature steel. AH36 steel plate and DH36 steel plate refer to the hot rolled steel plates produced according to the construction specifications of Classification Society for the manufacture of hull structures.
Due to the bad working environment of the ship, the hull is subject to chemical corrosion, electrochemical corrosion, marine organism and microorganism corrosion; the hull is subject to large wind and wave impact and alternating load; the shape of the ship makes its processing method complex.
Therefore, AH36 steel plate and DH36 steel plate are strictly required. Firstly, AH36 steel plate and DH36 steel plate are required to have good toughness;
In addition, AH36 steel plate and DH36 steel plate are required to have high strength, good corrosion resistance, weldability, processability and surface quality.
