Product Description
AH36/Z35 High-Strength Hull Structural Steel Plate
Engineered for Bulk Carrier Side Shell Integrity in Harsh Marine Environments
Product Overview
AH36/Z35 is a classification society-certified high-strength hot-rolled steel plate specifically designed for critical hull structures. Compliant with IMO CSR-H standards, it delivers superior load-bearing capacity and corrosion resistance for bulk carrier side shells exposed to dynamic wave loads and abrasive cargo impacts.

Core Advantages for Bulk Carrier Side Shell
1. Uncompromised Structural Safety
Wave Load Resistance: Withstands cyclic stresses exceeding 10^7 fatigue cycles (DNV RP-C203 verified).
Collision Protection: Absorbs 15% more energy than standard AH32 plates during grounding simulations.
2. Superior Corrosion Defense
Salt Spray Performance: Zn-Al-Mg coating option extends service life to 25 years (vs. 15 years for uncoated).
Cargo Abrasion Resistance: HV 150 surface hardness minimizes pitting from iron ore/coal impacts.
3. Fabrication Efficiency
Weldability: CET ≤0.42% enables high-speed submerged arc welding (SAW) at 2.5 kJ/mm without preheat (thickness ≤25 mm).
Cold Forming: Minimum bend radius of 2.5×t for shell curvature shaping.
