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.

DNV FH40 Steel Grade Specification:
Thickness: 4mm to 260mm, 
Width: 1200mm to 4000mm
Length: 3000mm to 18000mm.
