DH32 marine steel Description
DH32 steel is a kind of nbsp;hot rolled high tensile strength steel. Higher-strength ABS shipbuilding steel comes in 12 grades of 3 strengths, DH32 is one of the grades.The DH32 grade steel plates have yield strength of 45,500 psi (315 MPa), and ultimate tensile strength of 64,000 - 85,000 psi (440-590 MPa).
DH32 marine steel advantage
DH32 marine steel has good toughness, high strength, strong corrosion resistance, machining performance and good welding performance. Shipbuilding steel grade DH32 is used for shipbuilding and oil platform, and has been recognized by classification societies such as ABS, DNV, GL, BV, LR, NK and RINA. In addition, DH32 shipbuilding steel plates can be used to build structures with hull weights up to 10,000 tons
DH32 marine steel application
DH32 Shipbuilding steel plates are suitable for container and bulk cargo vessels as well as cruise ships, ferries and yachts.
