API 2H Grade 50 steel plates are intended for fabrication primarily by cold forming and welding. Plates produced to this specification are used for welded construction of offshore structures in selected critical sections that must exhibit good impact properties and resistance to fatigue and through-thickness or lamellar tearing. The primary use of these steels is in tubular joints,stiffened plate construction,and other intersections where portions of the plates will be subjected to tension in the through-thickness (Z) direction.
