Key Considerations of choosing a disc spring's material

- Load Capacity: Inconel 718 and 17–7 PH are suited for high-stress systems, while 51CrV4 and X10CrNi18–8 work in less demanding scenarios.

- Corrosion Resistance: X10CrNi18–8 and Inconel 718 excel in corrosive environments; 51CrV4 is less resistant unless treated.

- Temperature Resistance: Inconel 718 leads for high-temperature applications; 17–7 PH is suitable for moderate temperatures.

- Fatigue Life: Cyclic applications require Inconel 718 or 17–7 PH for durability.
