Introduction
GH4090(NIMONIC90) is an age-strengthened nickel-based deformed high-temperature alloy, British brand Nimonic90. The alloy has strong tensile strength, creep resistance, good oxidation resistance and strong reverse fatigue strength response. It is often used in mitochondrial disks, turbine blades and other parts, high-temperature turbines, sealing rings and high temperatures. GH4090 alloy spring wire is a high-temperature alloy cold-processed product with high strength and is mainly used to manufacture springs for aviation-related components.
