The EH32 shipbuilding steel plate is the mainly kinds of steel for shipbuilding and oil platform, the shipbuilding gradeEH32 can be used in the manufacture of the ship's hull structure, whose weight is more then 10000 tons. Shipbuilding grade EH32 is the high tensile strength steel, EH32 steel for shipbuilding and oil platform must be good toughness properties, higher strength, strong corrosion-resistance, the processing properties, and welding properties.
