FH40 shipbuilding steel plate is an extra high toughness marine structural steel grade designed for large vessels and offshore structures operating in severe environments.

Compared with AH40, DH40, and EH40 grades, FH40 provides higher impact toughness and improved resistance to brittle fracture, making it suitable for ships operating in extremely cold regions and challenging marine conditions.

With excellent weldability, strength, and fatigue resistance, FH40 helps improve the safety and service life of critical hull structures.

CEHE STEEL supplies FH40 shipbuilding steel plates with classification society certification, including ABS, BV, DNV, LR, and CCS.
