FH32/FH36/FH40
Thickness: 4mm to 260mm, Width: 1200mm to 4000mm Length: 3000mm to 18000mm.
FH32/FH36/FH40 High-Strength Marine Steel Plates
Product Overview
FH32, FH36, and FH40 are premium high-tensile marine steels certified by leading classification societies (e.g., RINA, ABS, DNV, CCS). Designed for extreme marine environments, these grades combine superior strength, exceptional low-temperature toughness, and corrosion resistance, making them ideal for critical offshore structures, polar-class vessels, and advanced maritime engineering.
Advanced Manufacturing
- Thermo-Mechanical Controlled Processing (TMCP): Ensures uniform mechanical properties and eliminates preheating for plates ≤30mm.
- Heat Treatment: Normalizing or quenching for thicknesses >50mm to optimize weldability.
- Surface Finishing: Shot blasting (SA 2.5 standard) and anti-rust coatings for corrosion resistance.
Applications
- Shipbuilding: Hulls, decks, and bulkheads (FH36); LNG carrier components (FH40); icebreaker vessels (FH32).
- Offshore Engineering: Oil rigs, subsea pipelines, and drilling platforms.
- Renewable Energy: Wind turbine foundations and underwater structures for offshore wind farms.
- Infrastructure: Coastal bridges, pressure vessels, and Arctic-class port facilities.
Certifications & Testing
- Compliance: Certified by RINA, ABS, DNV, CCS, LR, and 10+ global classification societies.
- Testing Protocols:
- Ultrasonic inspection for internal defects.
- Charpy V-notch impact tests at -60°C.
- CTOD (Crack Tip Opening Displacement) testing for critical weld zones.
Customization & Dimensions
- Thickness: 2–120mm (up to 300mm for special orders).
- Width: 1,500–4,000mm (ideal for large hull sections).
- Processing: Precision laser/plasma cutting, bending, and welding-ready edges.
Industry Advantages
- Extreme Low-Temperature Resilience: FH grades maintain toughness down to -60°C, outperforming standard marine steels.
- High Strength-to-Weight Ratio: Enables thinner, lighter structures without compromising safety.
- Sustainability: Reduces material consumption and CO2 emissions in large-scale projects.
- Micro-Alloy Innovation: Nb/V/Ti additions enhance weldability and fatigue resistance in harsh conditions.
