The RINA AH40 shipbuilding steel plates have yield strength of 390Mpa, and ultimate tensile strength of 510-650Mpa. All RINA AH40 shipbuilding steel plates are standard hot rolled carbon steels. All of these steels have been engineered to be optimal long-lived shipbuilding steels. Higher-strength RINA shipbuilding steel comes in 12 grades of 3 strengths, RINA AH40 shipbuilding steel plate is one of the grades.
RINA 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.
