GH4169 Superalloy Rod Fatigue Resistant for Aerospace Engine Components

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.
