FH690 shipbuilding steel plate is a high-strength marine steel grade with a yield strength level of approximately 690 MPa and enhanced low-temperature toughness.

It provides excellent strength, impact resistance, and weldability, making it suitable for critical ship structures exposed to severe marine conditions.

Compared with lower-strength grades, FH690 helps reduce structural weight while improving overall vessel efficiency.

CEHE STEEL supplies FH690 marine steel plates for shipyards and offshore engineering projects worldwide.
