DNV D690 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 D690 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. All the DNV D690 shipbuilding Steel offered by JoinWin Industry can be certificated by JoinWin as per customer's request.
