The primary components of **Inconel Tube Fittings** include nickel (up to 72%), chromium (14–17%), and iron, along with trace amounts of molybdenum, niobium, titanium, and aluminum, depending on the specific alloy grade. This unique composition grants them exceptional resistance to oxidation, carburization, and chloride stress-corrosion cracking. They exhibit a tensile strength ranging from about 650 to 1000 MPa and maintain impressive mechanical stability across a broad temperature spectrum. **Inconel** also offers excellent fatigue strength, weldability, and creep resistance, making it a perfect choice for high-pressure and high-temperature applications.
