Product Overview
Grade A/B/D/E hot rolled shipbuilding steel plate is normal strength marine structural steel manufactured to GB/T712 and ASTM A131 standards. This series includes Grade A, Grade B, Grade D and Grade E with graded low-temperature impact performance to adapt to different ocean service environments.
Grade A has no impact test requirement; Grade B features 27J impact at 0°C; Grade D reaches 27J at -20°C, while Grade E can maintain 27J charpy toughness under -40°C extreme cold marine conditions. The steel plate owns reliable mechanical property, good weldability and stable forming performance, widely used for ship compartments, hull auxiliary structures, barges and general offshore secondary structures.
We provide custom cutting, flattening and surface treatment service. All plates can be supplied with CCS, ABS, DNV, BV, LR ship classification certificates upon request. We support bulk orders and mixed container shipment, serving global shipyards, marine engineering contractors and steel traders.
