Key Features
- High-Temperature Stability: The addition of titanium helps stabilize the steel, preventing carbide precipitation and thus maintaining corrosion resistance at high temperatures.
- Corrosion Resistance: Excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 800-1500°F (427-816°C).
- Oxidation Resistance: Good oxidation resistance in intermittent service to 1600°F (870°C) and in continuous service to 1500°F (816°C).
- Weldability: Good weldability with no risk of sensitization due to the stabilization by titanium.
Applications
- Aerospace Industry: Used in exhaust systems and other high-temperature components due to their ability to withstand high temperatures and resist oxidation. Suitable for components in jet engines and gas turbines where high strength and resistance to oxidation are crucial.
- Chemical Processing Industry: Used in heat exchangers where hot corrosive fluids are processed, ensuring high performance and longevity. Suitable for reactors and pressure vessels dealing with high-temperature chemical reactions. Ideal for high-temperature distillation processes.
- Petrochemical Industry: Used in catalytic crackers, reformers, and other refinery equipment that operate at high temperatures. Suitable for components in furnaces and boilers where high-temperature stability is essential. Used in processing and storage tanks for high-temperature and corrosive liquids.
- Power Generation: Commonly used in boiler tubes and superheater tubes due to their ability to withstand high pressure and temperature. Ideal for heat recovery systems where efficient heat transfer and durability are required.
