High Temperature Rod
Product Details
GH4169 high temperature alloy rod is a precipitation-hardened nickel-based superalloy, renowned for its exceptional balance of mechanical properties across a wide temperature range. Its core composition includes nickel (50-55%), chromium (17-21%), and significant additions of niobium, molybdenum, and titanium—elements that work together to enhance strength, toughness, and stability. This alloy rod stands out for its ability to maintain structural integrity from cryogenic conditions (as low as -253°C) up to elevated temperatures of 650°C, making it a versatile choice for industries requiring reliability in extreme thermal environments.
Key performance attributes of GH4169 rod further solidify its industrial value. It boasts high tensile strength (typically 1,240 MPa at room temperature) and excellent fatigue resistance, critical for components subject to repeated stress, such as aerospace fasteners and turbine disks. Additionally, it offers strong creep resistance—meaning it resists deformation under long-term high-temperature loads—and good corrosion resistance, even in harsh settings like marine or chemical processing environments. Its weldability and machinability are also notable, allowing for precise fabrication into complex parts without compromising performance, which explains its widespread use in aerospace, power generation, and oil and gas sectors.
