| BV AH40 |
BV AH40 shipbuilding steel plate is a kind of high tensile strength marine steel. All of these steels have been engineered to be optimal long-lived shipbuilding steels. 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. All the BV AH40 shipbuilding Steel offered by JW STEEL Industry can be certificated by JW STEEL as per customer's request.
