DH690 shipbuilding steel plate is a high-strength marine steel grade with a yield strength level of approximately 690 MPa.

Compared with conventional shipbuilding steels, DH690 provides higher strength and improved structural efficiency, helping reduce weight and increase load capacity.

Its excellent toughness and weldability make it suitable for critical marine structures requiring long-term reliability.

CEHE STEEL supplies DH690 ship plates for shipyards and offshore engineering companies worldwide.
