High Temperature Rod
Product Details
GH4169 high temperature alloy rod is a high-performance precipitation-hardened nickel-based superalloy, prized for its excellent mechanical properties across a wide range of temperatures. It combines the perfect balance of strength, toughness, and stability, making it ideal for use in industries that require components capable of withstanding extreme thermal and mechanical stress. The alloy's primary composition consists of nickel (50-55%), chromium (17-21%), with added elements such as niobium, molybdenum, and titanium that work synergistically to enhance its overall performance. This makes the GH4169 rod a versatile and reliable choice for high-pressure vessel fabrication, aerospace, power generation, and chemical processing applications.
GH4169’s impressive mechanical properties ensure structural integrity across diverse thermal conditions, from cryogenic temperatures as low as -253°C up to high temperatures of 650°C. This alloy rod is perfect for industries requiring consistent performance in extreme environments. In addition to its thermal stability, GH4169 demonstrates high tensile strength (approximately 1,240 MPa at room temperature), superior fatigue resistance, and excellent creep resistance, all of which are vital for maintaining performance under continuous stress and high-temperature conditions. Furthermore, the material exhibits strong corrosion resistance, making it suitable for harsh environments such as marine and chemical industries.
Superior Material Composition: GH4169 is a precipitation-hardened nickel-based superalloy containing key elements such as nickel (50-55%), chromium (17-21%), niobium, molybdenum, and titanium. These elements significantly enhance the alloy’s strength, toughness, and resistance to temperature extremes.
Wide Temperature Range: The alloy is designed to maintain its structural integrity in cryogenic environments as low as -253°C, as well as at elevated temperatures of up to 650°C. This wide temperature adaptability makes it ideal for high-pressure vessels in extreme thermal conditions.
High Tensile Strength: With a tensile strength of around 1,240 MPa at room temperature, GH4169 alloy rod can endure high mechanical loads, ensuring durability in demanding applications.
