Applications

• Aerospace: Used in components of jet engines, turbine blades, and exhaust systems where both temperature resistance and structural integrity are critical.

• Power Generation: Commonly employed in gas turbines, boiler components, and other equipment exposed to high temperatures and thermal cycling.

• Petrochemical and Chemical Industries: Ideal for use in reactors, piping, heat exchangers, and other equipment exposed to corrosive environments and high temperatures.

• Marine: Nimonic90 is also used in marine applications requiring high resistance to saltwater and high thermal stability.

Manufacturing Process

1. Melting: High-purity raw materials are melted in an electric arc or induction furnace to achieve the desired chemical composition.

2. Casting: The molten alloy is cast into ingots, which undergo homogenization heat treatment to enhance uniformity and eliminate segregation.

3. Forging: The ingots are then hot-forged at temperatures above 1100°C to achieve the desired shape and improve mechanical properties.

4. Hot Rolling: The alloy is hot-rolled to reduce thickness and achieve precise dimensions while enhancing directional properties.

5. Annealing: To relieve internal stresses and improve ductility, the bars are annealed at temperatures around 900-950°C.

6. Finishing: Final machining, cutting, and surface treatments are applied to prepare the rods for their intended applications.

Advantages

• Superior High-Temperature Performance: Nimonic90 excels in environments with continuous exposure to high temperatures, making it ideal for aerospace, power generation, and petrochemical applications.

• Corrosion and Oxidation Resistance: The alloy's resistance to both oxidation and corrosion makes it suitable for challenging environments like marine and chemical processing.

• Strength and Durability: With high tensile strength and resistance to creep and fatigue, it ensures long service life in extreme operating conditions.

• Versatile Fabrication: Weldable and machinable, Nimonic90 can be fabricated into complex shapes and sizes, tailored for a variety of demanding industrial uses.
