Grade A Ship Hull Structure Steel

Grade A hull steel is used for shipbuilding hull structures and platforms. Grade A hull structural steel is an ordinary tensile strength steel with good toughness and high strength, strong corrosion resistance, processing performance and welding performance. Grade A hot steel plate can be used to manufacture hull structures of ships weighing less than 10,000 tons, usually used for navigation in coastal and river areas.
