Key Benefits

• Excellent low-temperature toughness, no brittle fracture under deep sea low temperature working conditions
• Balanced strength and ductility, ideal filler metal for Gr9 thin-wall hydraulic tube welding
• Outstanding saltwater corrosion resistance, stable performance in long-term offshore service
• Good fatigue resistance under cyclic pressure load for subsea pipeline accessories
• Lightweight alloy, reduces overall weight of underwater hydraulic assembly

Grade Description

Gr9 Ti-3Al-2.5V titanium alloy wire is specified under ASTM B863. It is a near-alpha titanium alloy famous for reliable low-temperature performance. Unlike TC4 Gr5 alloy which focuses on room temperature high strength, Gr9 retains good toughness at low temperature, making it the preferred material for subsea hydraulic tubing welding. Our Gr9 titanium wire is supplied to offshore oil and gas EPC projects in Norway, Brazil and Malaysia.

Product Features

Our cold drawn Gr9 titanium alloy wire is stress-relieved and pickled to remove surface oxide and residual stress. Every wire coil passes dimension inspection and strict chemical composition test to control aluminum and vanadium content. Gr9 titanium wire is mainly used as welding filler wire and small structural wire for subsea hydraulic pipelines and offshore corrosion-resistant components.

Industry Applications

• Offshore & oil gas: subsea hydraulic pipeline welding wire, underwater lightweight structural components
• Deep seawater circulating system, offshore platform corrosion resistant spare parts
• Offshore energy equipment fabrication projects in Norway, Brazil and Malaysia

Quality Assurance

Every batch undergoes strict inspection before shipment:

• Full dimension tolerance inspection
• Tensile, yield & low temperature impact mechanical property testing
• Chemical composition testing for Al and V content
• Material Test Certificate (MTC) supplied for traceability

FAQ

Q: What is Gr9 titanium wire mainly used for?
A: Gr9 Ti-3Al-2.5V wire is widely used as welding filler wire for subsea thin-wall hydraulic tubes and lightweight load-bearing parts on offshore platforms.

Q: What is the difference between Gr9 and Gr5 TC4 wire?
A: Gr9 features superior low-temperature toughness for deep sea. Gr5 TC4 has higher tensile strength at ambient temperature for aerospace and general high-strength parts.

Q: Does Gr9 titanium wire comply with ASTM B863?
A: Yes. Our Gr9 titanium wire fully meets ASTM B863 requirements and is accepted by offshore oil & gas engineering tender.
