Application

Engine Components: These are used in manufacturing high-strength, heat-resistant parts like turbine blades, discs, and rings.
Airframe Parts: These alloys serve for structural components that require high strength-to-weight ratios and durability under high stress and temperature variations.
Landing Gear: Components that need to withstand high stress and corrosion.
Gas Turbine Parts: These are for turbine blades, seals, and combustors where high-temperature strength and corrosion resistance are critical.
Nuclear Reactors: These materials are suitable for control rods, pressure vessels, and reactor cores due to their excellent high-temperature corrosion resistance and strength.
Drilling and Wellhead Equipment: Used in corrosive environments and under high pressure and temperature.
Piping Systems: For transporting hot fluids and gases in corrosive environments.
Reactors and Heat Exchangers: Components that require resistance to high temperature and corrosion by acids, gases, and other aggressive materials.
Pumps and Valves: For handling corrosive chemicals at high temperatures without degradation.
Propulsion Systems: For components that are exposed to seawater and require corrosion resistance and strength.
Naval Ships: In parts of ships, strength, corrosion resistance, and durability are necessary under marine conditions.
Exhaust Systems: Exhaust manifolds and turbocharger rotors are manufactured using alloys that can withstand high temperatures and corrosive environments.
Molds for Plastic Injection: Certain nickel alloys are used in making molds for plastic injection due to their excellent thermal fatigue strength, wear resistance, and ability to withstand the corrosive byproducts of plastics.
