BV AH40 Shipbuilding Steel Description:

BV AH40 steel is a kind of high tensile strength shipbuilding steel. All BV AH40 steels are standard hot rolled carbon steels. All of these steels have been engineered to be optimal long-lived shipbuilding steels. Higher-strength BV shipbuilding steel comes in 12 grades of 3 strengths, AH40 is one of the grades.

BV AH40 Shipbuilding Steel Application:

BV 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.
