Marine & OffShore
Steel Plate
API 2H Grade 50

An intermediate-strength, normalized, structural steel plate utilized in the welded construction of offshore structures. This grade is regulated by the American Petroleum Institute (API). Because of its specific restrictions, API has also been adapted in many other applications such as Base rings and Cylinders for Crane production, Piling for severe application on Bridge Construction and for “Fracture Critical” applications in areas where resistance to vibration and torque are necessary.
