AH32/DH32/EH32
Thickness: 4mm to 260mm, Width: 1200mm to 4000mm Length: 3000mm to 18000mm.
AH32/DH32/EH32 High-Strength Marine Steel Plates
Product Overview
AH32, DH32, and EH32 are advanced high-tensile marine steel plates certified by leading classification societies (e.g., RINA, ABS, DNV).
Designed for shipbuilding and offshore structures, these grades excel in strength, low-temperature toughness, and corrosion resistance, meeting the rigorous demands of modern maritime engineering.
Key Features
1. Mechanical Performance
- Yield Strength: ≥315 MPa (AH32/DH32/EH32)
- Tensile Strength: 440–570 MPa (AH32/DH32) / 440–590 MPa (EH32)
- Impact Toughness:
- AH32: 34J at 0°C
- DH32: ≥31J at -20°C
- EH32: ≥34J at -40°C
- Elongation: ≥22%, ensuring superior ductility
2. Manufacturing Excellence
- Controlled Rolling & Cooling (TMCP): Ensures uniform mechanical properties and eliminates preheating for thickness ≤30mm
- Heat Treatment: Normalizing or quenching for thickness >50mm to enhance weldability
Applications
- Shipbuilding: Hulls, decks, bulkheads (AH32)
- ; LNG carrier components (EH32)
- Offshore Engineering: Oil rigs, subsea pipelines (DH32)
- Specialized Vessels: Cruise ships, naval vessels, and polar-class ships (EH32)
Certification & Quality Assurance
- Certified by RINA, ABS, DNV, and 9+ global societies
- Testing Protocols:
- Ultrasonic inspection for internal defects
- Z-direction performance tests to prevent lamellar tearing
Custom Processing Services
- Shot Blasting: Delivers SA 2.5 surface finish for enhanced paint adhesion and corrosion resistance
- Custom Sizing:
- Width: Up to 4,800mm (ideal for large hull sections)
- Thickness: 4–260mm
Industry Trends & Advantages
- Shift to High-Strength Grades: Demand is rising for 5m-wide plates and 200–300mm thick boards for mega-container ships
- Sustainability: Reduced material usage due to higher strength-to-weight ratios
