FH40 Shipbuilding Steel Description:
DNV FH40 steel is a kind of hot rolled high tensile strength steel. The DNV FH40 grade steel plates have yield strength of 56,500 psi (390 MPa), and ultimate tensile strength of 74,000 - 94,500 psi (510-650 MPa). DNV FH40 steel can achieve the impact toughness at Celsius degree -60°. All the FH40 Shipbuilding Steel offered by BBN steel can be certificated by Det Norske Veritas DNV).
FH40 Shipbuilding Steel Application:
FH40 Shipbuilding Steel plates are mainly used for making the offshore oil drilling platform, the hull of ship building and ship repairing, the platform pipe joints and other components.
