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.
Classification Society Approvals:
ABS BV DNV GL CCS LR (Full set of mill certificates)
International Standards:
EN 10225 / ASTM A131 / JIS G 3106
Special Certification: Z35 (Through-thickness performance, guaranteed for >35% reduction of area)
| Parameter | Value |
|---|---|
| Yield Strength (min) | 355 MPa |
| Tensile Strength | 490-620 MPa |
| Elongation (A50, min) | 21% |
| Impact Toughness (CVN) | -20ºC: ≥46 J (Longitudinal) |
| -40ºC: ≥34 J (Transverse) | |
| Thickness Range | 6-100 mm (±0.3 mm tolerance) |
| Plate Dimensions | Width: 1,500-4,500 mm; Length: 6-18 m |
| Surface Quality | Class A (Per ISO 630) |
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.
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.
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.
