AH40 Shipbuilding Steel Plate

AH40 Shipbuilding Steel Plate

The steel grade AB/AH40 is ABS grade AB/AH40. It is equivalent with CCSAH40, BVAH40, NV A40, GL-A40, KRAH40, LRAH40, and RINA-AH40. AB/AH40 shipbuilding steel plate is a kind of hot rolled plate of higher tensile strength, with its minimum yield strength at 390MPa. It has excellent chemical and mechanical properties. AH40 is mainly used on shipbuilding and oil platform, and also in the manufacture of the ship's hull structure, whose weight is more than 10000 tons. It performs good in toughness properties, higher strength, strong corrosion-resistance, the processing properties, and welding properties.
