High Temperature Rod
Product Details
GH4169 high temperature alloy bar is a precipitation-hardened nickel-based superalloy, specifically engineered for applications requiring exceptional mechanical properties across a broad temperature range. Composed primarily of nickel (50-55%), chromium (17-21%), and reinforced with niobium, molybdenum, and titanium, GH4169 is highly valued for its strength, toughness, and thermal stability. Capable of withstanding extreme temperatures, from cryogenic conditions as low as -253°C to elevated temperatures up to 650°C, GH4169 is ideally suited for applications that demand high performance in both low and high-temperature environments.
Known for its high tensile strength (typically 1,240 MPa at room temperature), GH4169 offers excellent fatigue and creep resistance, making it ideal for components subjected to repeated stresses. Furthermore, this alloy offers superior corrosion resistance, even in aggressive environments such as marine or chemical processing applications. With its excellent weldability and machinability, GH4169 is frequently used in the aerospace, power generation, and oil and gas industries for critical components that require precise fabrication.
