DNV AH40 shipbuilding Steel Description
DNV AH40 steel is a kind of high tensile strength shipbuilding steel. All DNV AH40 steels are standard hot rolled carbon steels. All of these steels have been engineered to be optimal long-lived shipbuilding steels. Higher-strength DNV shipbuilding steel comes in 12 grades of 3 strengths, AH40 is one of the grades.
DNV AH40 Shipbuilding Steel Application
DNV AH40 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 AH40 Steel Grade Specification:
Thickness: 4mm to 260mm,
Width: 1200mm to 4000mm
Length: 3000mm to 18000mm.
