ASTM DH32 Steel Plate Products Description
ASTM Grade DH32 offshore steel plate is not only a high tensile strength steel, but also a hull structural steel with good toughness, higher strength, strong corrosion resistance, processability and good welding performance. Shipbuilding steel grade DH32 is used for shipbuilding and oil platforms. It is approved by ABS, DNV, GL, BV, LR, NK, RINA and other classification societies and can be used to manufacture the hull structure of ships under 10,000 tons.
ASTM A131 Grade DH32 weldable structural steel plates are corrosion-resistant steels suitable for manufacturing ship hulls, decks, offshore platforms, and marine port construction.
