API 2H Grade 42

API 2H Grade 42 is an intermediate-strength, normalized, structural steel plate used in the welded construction of offshore structures. API 2H Grade 42 has a minimum yield strength of 42 ksi [289 MPa] and a minimum transverse Charpy V-notch impact toughness of 25 ft-lb [34 J] at -40°F [-40°C].

Applications

API 2H Grade 42 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 42 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.
