Shipbuilding steel plates and sheets are generally manufactured from high-strength structural steel grades such as AH36, DH36, or EH36. They comprise controlled amounts of carbon, manganese, silicon, and trace alloying elements like nickel and chromium. These compositions provide excellent weldability, toughness, and corrosion resistance. Mechanically, they have a yield strength of 355 MPa and tensile strength of 490-620 MPa. Their high impact resistance, particularly at low temperatures, makes them suitable for marine and offshore environments where structural integrity is paramount.

Application Industry of Shipbuilding Steel Sheet and Plate

Shipbuilding Steel Sheets and Plates are mainly utilized in ship construction, barges, naval ships, and offshore oil platforms. Their higher mechanical strength and corrosion resistance qualify them for shipbuilding, decks, bulkheads, structural parts facing seawater and heavy loads. Outside the shipbuilding sector, they are employed in coastal structures, marine terminals, and dockyard machinery. Their long service life and security in mission-critical maritime and offshore applications are guaranteed by their durability, weldability, and tolerating adverse marine conditions.
