Nimonic 90 Bars and Rods are nickel-based superalloys primarily made up of nickel, chromium, and cobalt, with trace amounts of titanium and aluminum to boost strength and creep resistance. These bars showcase impressive mechanical properties, including high tensile strength, fatigue resistance, and stability at elevated temperatures reaching up to 980°C. The alloy also boasts exceptional corrosion and oxidation resistance, maintaining its structural integrity even under extreme thermal and mechanical stress. Nimonic 90 is well-suited for forging and machining, making it a versatile choice for precision-engineered components that need to perform reliably in harsh environments.
