Product Overview
AH32 / DH32 / EH32 / FH32 series marine steel plate is a high strength shipbuilding steel group manufactured in accordance with GB/T 712, ASTM A131 and equivalent marine material standards. This series is designed for ship hull structures, marine engineering components and heavy load-bearing parts where higher strength and low-temperature toughness are required.
AH32 provides basic high strength performance with room temperature or slightly low-temperature impact requirements. DH32 offers improved toughness at -20℃, making it suitable for vessels operating in colder environments. EH32 is designed for -40℃ impact conditions, while FH32 is intended for ultra-low temperature marine service down to -60℃. All grades in this series feature stable yield strength, good weldability and reliable structural safety.
Our AH32 / DH32 / EH32 / FH32 plates are widely used in bulk carriers, container ships, offshore platform modules, port machinery and heavy marine structures. We support custom cutting, flattening and edge processing services. All plates can be supplied with MTC and relevant classification society data according to your project requirements.

FAQs
The main difference is low-temperature impact grade. AH32 is for 0℃, DH32 for -20℃, EH32 for -40℃ and FH32 for -60℃. Yield strength is similar, but the choice depends on your operating temperature and design specification.
Yes. This series can be used for marine engineering components and heavy load structures. For critical offshore parts, please confirm the required impact temperature and classification data with us before ordering.
We can provide MTC and material data suitable for classification review. Actual certificate issuance depends on your project requirements and final mill document arrangement.
Yes. Mixed grade orders are acceptable. It helps shipyards simplify procurement and combine different low-temperature grades into one shipment.
Standard sizes are normally 18–28 working days. If you need specific classification documents or custom cutting, lead time will be confirmed after your formal inquiry.
Yes. All grades in this series are designed with good weldability. Normal shipyard welding procedures can be used, but preheating and welding parameters should be checked based on thickness and project specification.
