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.
Final chemical, mechanical properties, dimensions and tolerances are confirmed against the governing specification and purchase order.
