Comparison of Properties and Selection of ABS AH32 / DH32 / EH32 High-Strength Shipbuilding Steel Plates

AH32, DH32 and EH32 are all 315 MPa-grade high-strength shipbuilding steel plates certified by ABS. Their chemical composition, strength and elongation are essentially identical; the key difference lies in their low-temperature impact toughness temperatures (0°C / -20°C / -40°C), which determine their suitability for specific environments. DH32 offers the best value for money and is suitable for the vast majority of ocean-going vessels; EH32 is used in extremely cold waters; AH32 is used in warmer waters or for non-low-temperature structures.
