LR AH40 steel is a kind of high tensile strength marine steel. All of these steels have been engineered to be optimal long-lived shipbuilding steels.LR 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 LR AH40 shipbuilding Steel offered by China special steel limited can be certificated by JW steel's request.
