GR2 Titanium Plates for Ships

• Excellent corrosion resistance:Excellent performance in seawater, salt spray, and chlorine containing media, with an annual corrosion rate of less than 0.001mm. The surface dense oxide film (TiO ₂) can resist chloride ion corrosion and marine biological fouling, reducing the frequency of bottom cleaning and lowering maintenance costs by more than 50%.
• Lightweight and high-strength balance:The density is only 4.51g/cm ³ (about 57% of steel), the tensile strength is ≥ 343MPa, the yield strength is ≥ 275MPa, and the elongation is ≥ 25%. It can reduce the weight of the ship by 15% -30%, improve the speed and fuel efficiency, and meet the structural strength requirements of the ship.
• Outstanding low-temperature toughness:-Impact toughness>50J/cm ² at 196 ℃, suitable for extreme low temperature environments such as LNG transport ship storage tanks and polar icebreakers.

• Hull structure: The outer shell and deck have stable corrosion resistance in the high-pressure environment of 5000 meters deep sea. For example, the Russian "North Wind God" class nuclear submarine uses titanium alloy welded hull.
• Power system: Propulsion shaft and seawater pipeline. The Chinese "Xuelong 2" polar research vessel uses Ti-631 titanium alloy shaft system, which is resistant to low temperature -50 ℃ and has a 3-fold increase in anti cavitation corrosion life.
• Auxiliary equipment: condenser tube bundle, ballast tank liner, capable of withstanding high pressure up to 5000 meters deep in seawater desalination equipment.

Technical Parameter

• Chemical composition: residual Ti, Fe≤0.20%,O≤0.18%, Compliant with ASTM B265 and GB/T 3621 standards;
• Working temperature: -253 ℃ to 350 ℃;
• Certification support: ISO 9001 certification.

Quality Assurance

• Adopting vacuum consumable arc furnace melting+multi-directional rolling process, the grain size is uniform and dense, and the entire process passes ultrasonic testing and third-party mechanical property testing.
• Choosing this product can replace traditional stainless steel and copper nickel alloys, reducing equipment weight by 15% -30% while extending service life by more than three times, providing a reliable solution for high corrosion and high stress scenarios in ships and marine engineering.
