As a high-end product of high-strength marine steel, DH40 ship plate is the core support material for the construction of various special ships. Its composition is precisely designed. On the basis of strict control of impurity elements, by optimizing the ratio of micro-alloy elements such as niobium, vanadium, and titanium, and combining with advanced controlled rolling and controlled cooling technology, the yield strength of the steel reaches more than 390MPa and the tensile strength exceeds 510MPa.
From the perspective of characteristics, DH40 ship plate has super comprehensive performance. It not only has extremely high strength and toughness, can maintain structural integrity under extreme conditions, but also has excellent low-temperature toughness, and still maintains good impact resistance in an environment of minus 40℃. In addition, its excellent weldability and formability can also meet the construction needs of complex structures.
The advantage of DH40 ship plate is that it meets the stringent requirements of special working conditions. With its ultra-high strength, it can significantly reduce the ship's deadweight and increase its payload; its excellent low-temperature resistance makes it the preferred material for special ships such as polar ships and marine research vessels; its excellent welding performance ensures the reliability and safety of the ship structure.
In the application field, DH40 ship plates are mainly used in special ships with extremely high performance requirements, such as icebreakers, luxury cruise ships, large marine engineering operation ships, and key parts of some military ships. Whether in the polar cold environment or in complex marine engineering operations, DH40 ship plates provide solid protection for the safety and efficient operation of ships with their excellent performance.
