Ti Grade 9 (Ti 3Al-2.5V) is a titanium alloy with excellent resistance to seawater corrosion and higher mechanical properties than stainless steel. The characteristics of Ti-3-2.5 alloy include:
Excellent resistance to seawater corrosion
High mechanical strength and excellent strength-to-weight ratio
Excellent resistance to stress corrosion cracking in chloride and acidic gas environments
Excellent resistance to pitting, crevice corrosion, and erosion corrosion
Good formability and weldability
Extremely low coefficient of thermal expansion

Applications
Ti-3-2.5 as a cold-worked and heat treated titanium alloy provides excellent service in aggressive chloride-containing environments. Typical applications are:
Oil and gas industry
Chloride environments such as seawater handling and process systems and hydraulic and process fluid tubes in umbilicals.
Seawater cooling
Tubing for heat exchangers and coolers on oil platforms, in refineries, chemical industries, process industries and other industries using seawater or chlorinated seawater as coolant.
Refineries and petrochemical plants
Tubes and pipes where the process environment contains a high amount of chlorides or sulfides.
Geothermal wells
Heat exchangers in geothermal exploitation units, systems exposed to geothermal or high-salinity brines, tubing and casing for production.
Pulp and paper industry
Tubing for chloride containing bleaching environments.
Desalination plants
Tube and pipe for seawater transport, heat exchanger tubing, and pressure vessels for reverse osmosis units.
Mechanical components requiring high strength
Propeller shafts and other products subjected to high mechanical load in seawater and other chloride-containing environments. Excellent mechanical and corrosion resistance properties make Ti-3-2.5 tubing and pipe an economical choice for many other applications by reducing the product life cycle costs of equipment.
