EH36 shipbuilding steel plate is the main variety of steel for shipbuilding and oil platforms, shipbuilding grade EH36 can be used to manufacture hull structures weighing more than 10,000 tons. Shipbuilding grade EH36 is high tensile strength steel, EH36 steel for shipbuilding and oil platform must have good toughness, high strength, strong corrosion resistance, processing performance and welding performance.
EH36 shipbuilding steel plate specification:
Thickness: 6mm to 240mm, Width: 1500mm to 4020mm, Length: 3000mm to 27000mm.
