High-tensile structural steel grades such as AH36, DH36, and EH36 are used in the production of shipbuilding steel sheets and plates. Carbon (≤0.21%), manganese (≤1.70%), silicon, and alloying elements like copper, nickel, and chromium to improve toughness and corrosion resistance are usually included in their chemical composition. These plates have tensile strengths between 400 and 620 MPa, a yield strength between 235 and 355 MPa, and good weldability. They are dependable materials for demanding naval applications because they provide outstanding impact resistance at low temperatures and maintain mechanical integrity under high stress and in corrosive marine environments.

Application Industry of Shipbuilding Steel Sheet and Plate

Ships, barges, marine vessels, offshore platforms, and floating structures are the main applications for shipbuilding steel sheets and plates. They are necessary for the construction of bulkheads, engine rooms, decks, hulls, and superstructures. They are appropriate for both commercial and military vessels due to their high mechanical strength and resistance to corrosion. Additionally, these plates are used in port equipment fabrication, naval refit, and ship repair. Long service life and lower maintenance costs are supported by shipbuilding steels, which are made to withstand the demanding conditions of saltwater, pressure changes, and wave impact.
