Titanium grades suitable for high-temperature applications include:
Grade 5 (Ti-6Al-4V): This is the most commonly used titanium alloy, known for its high strength, lightweight, and excellent corrosion resistance. It has good high-temperature performance up to 600°F (315°C) and is used in various aerospace and industrial applications.
Grade 7 (Ti-0.15Pd): This grade offers a similar strength as Grade 2 with improved corrosion resistance due to the addition of palladium. It has good high-temperature performance up to 800°F (425°C) and is used in chemical processing applications.
Grade 9 (Ti-3Al-2.5V): This alloy offers a good balance of strength, ductility, and corrosion resistance, with better high-temperature properties than Grades 2 and 7. It can be used at temperatures up to 600°F (315°C) and is commonly used in aerospace and automotive applications.
Grade 23 (Ti-6Al-4V ELI): This is essentially a higher purity version of Grade 5, which offers improved fracture toughness and ductility. It has a similar high-temperature performance to Grade 5 and is commonly used in aerospace and medical applications.
Ti-1100: This is a high-strength, high-temperature titanium alloy designed to withstand temperatures up to 1100°F (593°C). Its applications include jet engine components and high-speed airframe structures.
It is important to note that the choice of titanium grade for high-temperature applications will depend on the specific requirements of the project, such as the maximum operating temperature, stress, and other environmental factors.
