Since the advent of the jet engine, titanium has been used in new alloys and production techniques to meet ever tighter standards for high-temperature performance, creep resistance, strength, and metallurgical structure.
Titanium is used for critical jet engine rotating applications. In the newest technology jet engines, wide chord titanium fan blades increase efficiency while reducing noise.
In the airframe structural market, innovative alloys replace steel and nickel alloys in landing gear and nacelle applications. These substitutions enable airframe manufacturers to save weight and improve aircraft efficiency.
With each new design, commercial aircraft manufacturers increase the use of titanium in airframes.
Titanium forms a very tenacious surface oxide layer, which is an outstanding corrosion inhibitor. In many harsh environments it can outlast competing materials as much as 5:1. Lower failure rates translate to less downtime, reduced maintenance and total lower cost. As a result, titanium has found a home in numerous industries ranging from power generation to chemical processing to desalination plants.
In power generating plants, where saline, brackish or polluted waters are used as the cooling medium, titanium thin wall condenser tubing will last for the life of the condenser (with a 40-year warranty against failure under proper conditions) and eliminate the need for a corrosion allowance.
Many chemical processing operations specify titanium to increase equipment life. It offers lifecycle cost advantages over copper, nickel and stainless steel grades, while providing initial cost advantages over materials such as high nickel alloys, tantalum and zirconium.
In petroleum exploration and production, titanium pipe's light weight and flexibility make it an excellent material for deep sea production risers. In addition, titanium's immunity to attack by sea water makes it the preferred material for topside water management systems. It is used on existing platforms in the North Sea and many more projects are in the planning stages. And since it shows virtually no corrosion in salt water, titanium is also the material of choice in desalination plants worldwide.
Titanium alloys are used in dozens of other industrial purposes, such as flue gas desulphurisation for pollution control, PTA plants for polyester production, pressure vessels, heat exchangers, and hydrometallurgial autoclaves. Each grade is tailored to specific operating conditions, emphasizing strength for different pressures, alloy content for different corrosive agents and ductility for different fabrication requirements
