ABS grade AH32 is equivalent with CCSAH32, BVAH32, NV A32, GL-A32, KRAH32, LRAH32, KA32, and RINA-AH32. AB/AH32 shipbuilding steel plate is a kind of hot rolled high tensile strength marine steel plate. Its minimum tensile strength is 315MPa.
AB/AH32 shipbuilding steel plate is ideal for the offshore oil drilling platform, the hull and ship repairing. More specifically, the thin but wide plates are used for shipbuilding applications to offer the best processing properties, such as flatness and weldability. In contrast, the thick high-strength thermo-mechanical rolled shipbuilding plates are used in offshore applications.
