DNV Grade B steel is a kind of high tensile strength marine steel. All of these steels have been engineered to be optimal long-lived shipbuilding steels.DNV Grade B 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 Grade B (NVB) marine steel plates are used in manufacturing hull, maritime oil extraction drilling platform,platform tube junction and other structural components.
