API Spec Grade 2HGr42 Offshore Platform Steel Plate Description

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]. API 2H Gr.42 grade steel is a type of high-strength structural steel that is commonly used in offshore platforms and structures. It is specifically designed to meet the requirements of the American Petroleum Institute (API) for offshore applications. The dimensional steel plate range of our supply in API 2H Gr.42 grade steel typically includes thicknesses ranging from 1/4″ [6mm] to 6″ [150mm], and widths ranging from 60″ [1500mm] to 160″ [4020mm]. This steel grade offers excellent weldability and toughness, making it suitable for demanding offshore environments where strength and durability are crucial. Its dimensional range ensures versatility in various construction applications, enabling the fabrication of robust and reliable structures for offshore operations.

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.
