API 2H Grade 50 is an intermediate-strength, normalized, structural steel plate used in the welded construction of offshore structures. API 2H Grade 50 has a minimum yield strength of 50 ksi [345 MPa] and a minimum transverse Charpy V-notch impact toughness of 30 ft-lbf [41 J] at -40°F [-40°C]. SSAB is an API Licensee under the API Monogram Program. This product can be multi-certified to ASTM A633 Grade C, ABS DH/EH 36, ASTM A537 Class 1 and MIL-S-22698 Rev C in thicknesses to 2" [50.8 mm].

Applications: API 2H Grade 50 is intended primarily for use in offshore structures in critical portions that must exhibit good impact toughness and resistance to plastic fatigue loading and lamellar tearing. The primary use of API 2H Grade 50 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.
